CSEC Maths May 2026 P1 Solutions In-depthAdded:
with salsa. With salsa, >> let me head out. I'm trying not to be too loud. I can't talk to >> talking real loud.
>> All right.
>> Am I live on YouTube?
Yep.
We are live on YouTube. Let me share my screen and we go. Let's go. I going to do the solutions kind of in depth cuz I feel like people going to use it later on. So real fast.
All right.
>> For the future generation.
>> Say that again.
>> All right. Let me start right. So the first question.
Oh god. Don't tell Apple dead. Don't tell dead. What? No. No. No. No. No. No.
No. Why? Why are you dead?
>> Oh my god.
So, what's your back? What was your backup?
>> I feel like we had to buy like a box of Apple Pens and just have them charge.
>> All right. All right. All right. I have the I have the fake Apple Pencil to the rescue.
And the thing is when I using the fake Apple Pencil, I can't charge the other one. How do I make sense?
>> That maximum maximum.
>> All right, let me go.
>> 13.
>> Will it work? Yeah. So - 3 squar that's 9 - 2 square 2 that's 4 9 + 4 is 13 1 d 1 dile when I see that question >> 0.45 45 over 100 >> 9 food.
>> This is how I repeat too. I add 2/3 to one/3. Get another one.
>> 2/3.
>> Food.
>> Two3.
>> All right. Easy.
Right. Um, this is a repeat too. Yeah.
>> And that's how I get the answer.
>> Right. Is that a good way to do it? Um, this was a nice question as well.
>> I see this question before, but they change it up slightly. They change it up slightly. Right.
>> The answer >> is A.
>> Um, the answer is not 250. It's not 250.
The answer is actually C. The answer is actually C.
>> The answer is actually C.
>> Let me explain something. Right. Wait, wait, wait. Let me explain something.
Oh, let me explain something. They're saying umpires are paid a flat fee. If it's a flat fee, did they play anything as yet? Like, watch, watch. Umpires are paid a flat fee up front for appearing.
Just for appearing. If it's just for appearing, did they play any matches yet?
>> No.
>> No. So, here we are to backtrack. We had to backtrack, right? Um, so if 3 is 2,250 and you realize that you're adding 250 repeatedly, then if I going back I would have to do what?
>> Minus 250 >> minus 250.
>> So So two number of matches two going to be 2,00 >> then one could be 2,00 no 1,750.
>> Ah, and but but but remember it's just for appearing. So they didn't play our matches yet. So we had to go back even more.
>> Yeah. One more time.
>> 1,500.
>> 1,500.
>> And so you couldn't get 1500 if you divide. I was thinking >> I had that first.
>> And this is just because just they just because they appear. They just because they appear, right? Just because they appear. By the way, guys, don't forget to share the link all over the place. I mean like the YouTube live, right? Share the YouTube live. All right. So So five was C. Five or C. Anybody get that correct?
>> I get correct. I had I erased it and put C.
>> I had >> because sir, I was like, how you going to charge a whole 1,500 fine?
>> Why you charging, 1500 just >> Exactly. Because I I I divided it and I was like, "Okay, 1,500." I put See, I was like, "Sarah, read this thing again."
>> But is it like It's just for appearing.
It's literally just for appearing. is just for appearing, right? We we have done questions like this, remember like you have a fixed you have a fixed fee just for appearing >> and then every every like it iteration you're getting that same rate. So we could see that is a fixed like it start off at 1,500 then if they play the first march jump up to 750 then 2,000 then yada yada yada five was C right six the answer for six was B was actually B let me explain why um umpire A officiates at 10 games while umpire B officiates at six and they want us to talk about the ratio of their earnings here's a mistake somebody would have make I know a lot of you guys would go in the exam and you put 10 by six and you would say 5 by three. Five to three.
That's wrong. That's wrong.
>> I did that.
>> That's wrong.
>> It's the ratio of their earnings. So, we have to find So, we have to find their earnings. Let me show you how we could do that. So, I'm not sure if you all recognize, but this is an arithmetic progression. um all arithmetic progressions could be um you could you could generalize it by saying um a + n minus one d where a is the first term and d is just a common difference right so here what if we want to calculate the amount of earnings for 10 games um tell me what was the fixed amount was the fixed amount guys was the initial starting what we start off with initially initially >> 1 1500 >> 1,500 Right.
If I going up to the 10th game, that'll be 10 - 1, which is nine. And where's the difference?
>> What's the difference? So, like to go from from like the third to the fourth to the fifth, where's the common difference? There's a common difference, right? I plug this into my calculator.
All right.
I'm going check a6 now.
That'll be 6 - 1 which is five.
Something sus is happening here.
>> Yeah, right.
This is very sus.
This is very very sus.
when I had >> wait so like I know the answer is the cuz I had done the questions already but when I had done it oh okay okay I understand the All right. Your car say n minus one.
It's it's not like okay in this instance since we start off with a fixed amount.
Um okay since it started off with a fixed amount right when when I say n minus one in accounting for that fixed amount to start off with. So if I add back the starting amount what I what I get if I add back the starting amount what I get?
>> Um >> what is 3750 plus 250?
>> 4,000. 4,000.
>> Yeah.
>> 4,000. Right. And um what is 2750 plus 250?
>> 3,000.
>> 3,000.
>> Right. And they said like A to B, right? A was 10 games. For 10 games it was 4,000 and um six games it was 3,000. So that's a what ratio?
>> Four to three.
>> Right. And if that confusing you, I mean, if you can move like a mad man and manually count calculate it, but that's crazy. But here what? Let me show you how we work it out, right? Like if you didn't want to use this formula or anything, let me show you how it'll work it out fast. So we already have the six game, right? So how much did they earn for six games?
>> 3,000, >> right? So they already gained 3,000 over here, right? Let's keep going.
So the seven game what be >> 3,000 plus 250 >> come fast >> 3,00 game what be >> n500 4,000 no wait no 50 >> right 3750 and in the 10th game what are we >> 4,000 >> 4,000 So look at it for yourself. In the 10th game, you would have earned 4,000 and in the sixth game, you would have earned 3,000. What's that ratio?
>> Four to three. Four to >> four to three. Four to three.
>> How much of you guys got that? How much of you guys got that? 6ata.
Yeah.
>> Um, sorry, I guess it correct.
>> No, Sarah, why you put >> I put C sir because I did exactly what you said like you times it by so and so cuz I was like wait. And then the same thing with the first one. I thought it was 250. Even though when I divided I got 1,500. I said that's impossible.
>> And I wait.
I'm sure you will do. I'm sure you will do.
>> Doubt yourself.
Wait, let me check YouTube. Let me see on YouTube. How many on YouTube?
57 people on YouTube.
Yeah, guys. So, it is 6B 6B 4 to 3, right? Everybody okay with that?
>> Yes, sir. If you're using the um if you're using the A of N formula, you'd have to add the 250 to you'd have to add the 250. You'd have to add the 250, right? But I wouldn't recommend doing all that. They could just do this until you understand this. I can just add in 250. Easy, right?
All right. Let me move on to this one.
Um All right. Seven. The number of possible subsets of M is H. So we have M here. So is the formula to find the number of subsets?
>> Two by the number of set the number of elements >> there are three elements there.
>> So two to the power three is >> so two eight >> eight 7D I get that right?
>> Yes sir.
>> Yes ma'am.
>> All right cool.
They want me to figure out the number in m intersect n complement. So like let's determine what n complement would be first. Right.
So you have a universal set and a universal set is P, Q, R, S, and T.
So maybe I could draw a vin diagram and it would make sense for you guys. Let me draw draw a ven diagram.
What's the bigger what's the bigger um what's the bigger circle going to be?
What's that going to be?
>> M.
>> It's going to be M, right? And inside that you're going to have what?
>> N going to have N. And inside that you're going to have PQ. And for Emma alone, Emma alone only what?
>> R.
>> R. And outside all they have >> ST. >> Wait have a N here. Yeah. PQR.
Oh, I have N there to represent N, right? Um, the only person that we did not count for was S and T, right?
>> Yes, sir. Yeah.
>> All right. Are we talking about M intersect N complement? So N complement would include everything like what?
>> R or S and It would include R. Yeah. R what?
>> ST. >> R S&T. Well, let me ask you a question immediately. Right. If it is M intersect N complement N complement would be everything other than PQ. So would it would it have any intersecting elements?
>> No sir. No sir.
>> No. No. No. The answer is zero. The answer is zero. You got you guys got this one.
>> No, I bought one.
>> I bought one.
>> Let me explain it back again. Right. Let me explain it back again. I know they done the exam already, but still want to explain it back here. What if we talking about N complement? What are the elements in N complement?
N nothing let me just run it back again. So N complement what would N complement be?
>> R >> if it is N complement >> R T >> right and we talking about that intersecting with M. M is PQR. Yeah you would have R. You have R. I'm not sure why you're seeing that. So it would be one because in in M you actually have PQ and R and if we talking about N complement would be >> PQ.
>> N complement is R S and T.
>> Oh okay. Okay. Okay.
>> Are there any intersections here?
>> Yes. R >> R. So my bad. It's actually one. It's actually one.
I get scared.
>> I was scared too. I was like, I don't think I get this simple one wrong.
for one, right? You guys pull one >> for one, right?
>> Yes.
>> Yes. So, I literally correct my >> because N complement was R, S, and T.
So, you have a R and N complement and in M you have R. You have a R and R there.
So, that's one. They have one thing in common. Um, which of the following statements about sets M and N is true?
Well, I guess all they could see it here, right? But, um, you would say that what would you say? Which one is true?
N= >> M M union N is M >> is M.
>> That's that's correct because watch if I combine the elements in M and N what are going to be >> m >> that would just be PQR >> which is M.
>> Mhm.
>> So that's going to be the B. You guys put B.
>> Yes sir.
>> Yes sir.
>> Okay good. Um is I repeat the answer is um Q R >> right Q Right.
Um is that repeat as well?
>> You're looking real bad. But this was the 36%.
>> Yeah.
>> The 48% question.
>> It would be B 16.
>> Yeah, it would be B 16. Right. So yeah, it's 16, right? Because 36% playing Scrabble only, 48% playing checkers only. So then the intersection would just be 100 - 36 + 48 and that be 100 - 64, which is 16.
You guys got that right?
>> Yes, sir.
>> Yes, sir.
>> Yeah. Boy, I'll be 84. Yeah. 100 - 84 is 16.
Um, how many students play tennis but not chess?
So they're playing tennis but not chess.
So if they're playing tennis but not chess, what's the only thing they're playing?
>> Tennis.
That's Ali, Alex, and Kayla. That's so four.
>> 12 C.
>> Yeah. 12 C. Everybody got that.
>> So if you put six and minus two, would that be correct?
>> Yeah, that's correct.
>> You get four.
>> Yes, sir. Um, all right. Does that repeat? What's the answer?
>> D was the answer. I put D, right?
>> Yes, sir.
>> I believe so.
>> I think so.
>> Cuz I never >> cuz that's the highest, right? Cuz everything elimination for this one.
>> Everything more than 1850.
>> Exactly. Think about it. If you're paying 5% sales tax, are you going to pay less than 1850 or more than 1850?
>> 1850.
>> Oh, the only one that makes sense is D.
Right.
Um >> 10.
>> This like a slightly new question.
>> 10.
>> 10.
>> Yeah, that just be 10 because >> we just multiply $2.50 by 10 to get 25.
Can like I repeat >> see 102 is 102 >> 102 >> this is question >> wait are you sure read back the question again for my >> wait take your time for every 100 in sales or part thereof off you see in that part read that again for me >> or 100 in sales or a part there off >> a part there off you know what I mean right >> that I mean If it le 100 years counted.
>> Yeah.
>> Yeah.
>> Wait. So is D then?
>> D. Let me explain it back again. Right.
They say for every $100 in sales or a part thereof. So when I go when I do, 120 divided by 100, right? I'm going to get 10.2. Will you agree?
>> Yes, sir.
>> Yes, sir. So you going to say 10 by 10 which is 100 and you have a path that path there off you're going to get paid how much?
>> $10.
>> $10.
>> Yes. D. Anybody put D?
>> Oh sir.
>> I want this.
>> You know there's hope. There's hope.
There's more to go.
>> How it looking? How it looking?
I have I have a sally right now >> 1 to 17 take half an hour to do >> we had to continue but um the answer 15 was D right 110 because it was part off um the annual interest rate on a mortage for a house assessed at a value of 450,000 is a repeatance >> yeah what was the That >> B.
>> That was um B, right? That was B for boy.
>> Yeah, B for boy. Cuz you just find you would just find um five all over 100 by 450,000.
>> Yes, sir.
>> And 45 400 4500 by five. That would give you answer, >> right?
Yeah. And immediately just think about it like this. Okay, you can round this off to like 4,000, right? Where's 5 by 4,000?
>> 20,000.
>> Where's the closest answer to 20,000?
>> 22,000 >> B. Right. So, 16 B.
>> Yeah.
>> Um, the value of a plot is repeat.
What's the answer?
>> D.
>> Is that >> D? Right.
>> D. I remember cheap 126, right?
>> Question. Yeah, it was 126.
>> My god, >> I can't remember why.
>> All right, I'll be back again real fast.
So, you find you have how much 100 you have in 1800? You have 100 You have 180, right?
>> Yes, sir.
>> And then you're going to find 0.7 on this. You could just multiply this by 7.
0 by 7 is zero. Where's 8 by 7? Is that not 56?
>> 56. Yeah.
>> Then you move your decimal place here.
126 >> greatness, >> right?
18. There's a repeat, I think.
>> Is it? Is it looking a little different?
>> They change the they change the numbers.
So, at 10, it would be nine.
>> Yeah, it's nine now.
>> All right. What are we doing?
>> All right. So, a man's basic wage for a 40hour week is 600. He's paid over time at a rate of one and a half times the hourly rate here. Well, I find the hourly rate first. Right. So if it's 40 hours and he gets paid 600 to find for 1 hour we divide both sides by 40. So 1 hour is going to be 600 divided by 40. 4 into 60 is 15 right?
>> 15. Yeah.
>> Yes sir. Well >> do math on the calculator.
>> Yeah.
>> And what would what would one and a half 15 be?
>> So 1 by 15 is 15. What is half of 15?
>> 7.5.
7.5 >> and 15 + 7.5 is >> 15.
>> All right. So, if he works overtime, he gets paid at this rate, 22.5.
Um, what is his total wage for a particular week? Um, they're telling you it was $82.50.
So, he had a work over time for $22.50.
>> Yes, sir.
>> Immediately the answer like Wait, so you got to be careful. Um, let me be careful. So, now we have to do some division.
I use my calculator fast. I don't want to hurt my head.
That's nine.
>> Let's put the lowest one.
>> Yes, sir.
>> Like, okay, let me explain something, right? Let me explain something. If it was um if it was 20 If it was 2250 divided by Okay. Okay. If it was 225 by 22.5, what do you think the answer would that be?
>> That'll be 10.
>> 10.
>> That would be 10.
>> But not this is a little less than 10.
So what you had to be?
>> It'll be nine. Yeah.
>> Be nine. Yeah, >> I think I understand that.
>> I can't remember.
>> So I believe >> 18 was a 18. It was a >> 18.
>> All right.
Get out now.
>> Yeah, I get I think >> I can't remember that blue. So, so far I believe I got two wrong.
>> Okay. Um, the simple interest does it look like I repeat, is it not?
>> 600.
>> Yes, sir.
>> The sum of money >> is 600.
>> I'm do back fast. So, the interest is 90. Um, we don't know what the principal is. The raise is five. The time is three all over 100. Um, when I multiply both sides by 100, that'll be 9,000.
And that'll be 15.
Yes, sir. Divide it and you get 600,000.
Yeah.
>> Yeah. Yeah.
>> Yes, sir.
>> All right. At a sale, Jack bought a bat for $36. The price included a 10% discount.
>> 40, right? That >> right? Because like if if the 10% discount is already accounted for, that'll be 90% final. 90% is 36. Um, you divide both sides by 90.
1% is actually 36 over 90, which is which is what?
9 into 36 is 4. 9 into >> 10 is 10. That going to be 4 by 10. You multiply by 100 on both sides.
>> I got 0.4 by 10 by 100.
4 by 10 is 40.
>> 20d 20.
>> Yes, sir.
Right. 20d >> um 3 by 2 is six. Does that repeat? X^ 5.
>> Yeah. Yeah. I get >> I answer question asked me and I >> Nice. And there's a repeat. What's the answer?
>> A repeat. Yes. Oh yeah. Yeah. I remember after I start flying through these, bro.
Yeah. Yeah. Like this is the section.
This is the other section, >> right? This a repeat. Hey, we do this question. We do this question last night.
>> It was slow mention.
>> Ah, let me go. Let me >> go back what you said. I did what you said like just look at the closest. I was like, wait, Sarah, it's D cuz it has to be closest to whatever it is. I was like, yes.
>> So, I use your >> All right. So, like check it check it fast, right? Um with 5 kg it stretched to 31. We could approximate that to 30, right? Approximate to 30 >> and like we could approximate that 29 to 30, right?
>> Yes sir.
>> Now it looked like it increasing like okay 5 kg by 30 is is is okay that's 30, right? And it look like we increase the mass by how much times?
>> Six.
>> Six.
>> So what's the answer guys?
Um yeah.
>> Yeah.
>> Another way you can do it. And check this is this is the other cool way you can do it. Where's five by? Okay. Five by what is 30?
>> Five.
>> So you multiply this by six.
Oh >> I I just divide 31 by five.
>> Badness. Badness.
>> I divide 31 by five and multiply by 29.
That's not a problem. But the answer was 23D people. You guys got that? Yes, sir.
Yes, sir.
>> So, as soon as I saw this question, I remember what you was talking about how you could get 4.6.
>> Yes.
>> I like that.
>> January.
>> January question in this paper from >> January. Yeah. Sir, one more time.
>> Repeat. Yeah. Nikolai.
>> A+.
Yeah, this one was a I remember Cassidy was getting trouble with this one. But >> she's getting trouble.
>> Yes. You remember? You remember? She couldn't Well, my bad for >> She got through. She got through with this.
>> No, before I remember.
>> Yeah. Remember she I didn't get any problems with it. I just mix up their names.
Exactly. Nikolai beef. You already got >> cuz 2 * 2 * 3 is six.
>> Is that repeat, >> right? Cuz >> right.
>> So I I need rest. I tell I need rest, right? Like right now my brain working like how it was working that first like I real tired. Oh no. Like I real tired.
I'm real tired out there. So like I contemplating if I should do a physics live tomorrow.
>> Tomorrow.
>> I think I need my rest. I think I need my rest. I think I need my rest.
>> Take your rest.
>> Take your rest today. And you >> maybe later not. So yeah, you need to sleep soon.
>> Chemistry.
>> Chemist on Saturday. But >> see that I just write 12 over here.
That's crazy. I tell >> I real tired.
>> Saturday.
>> Saturday. Saturday. Chem is on Saturday.
>> Oh, it's on Saturday.
>> Oh, let me finish this fast. I want to sleep.
>> Okay, >> this was a this was a easy one, too. We had this.
>> Cad is equal to three, right?
>> And they're telling you that A is equal to six. So, that'll be 3D is equal to 6.
So, B will be equal to two. All right.
Um they will be to find a squ - b square.
>> Yes sir.
>> Um that will be 3^ 2 - 2 that will be 9 - 4 9 - 4 is 5.
>> Yeah I think that >> all right cool. I love this question.
The answer is a right.
>> I just multiplying every single thing by three. Everything by three.
>> Everything by >> Yeah. Yeah. I fly through this week.
>> Right. the determinant >> I 40 this 42 >> minus two I remember this battle >> right um the vector P minus Q is represented by >> is that repeat as well remember this one >> yes >> 52 >> minus 52 52 >> 52 >> 52 >> yeah 52 too. Are we okay?
>> Yeah. Yes, sir.
>> You see number 30. You see number 30.
Like >> number 30 was physic.
>> I put B.
>> It's B. Right. Let me see.
>> Which of the following diagrams best shows the resultant sum of the forces F_sub_1 and F_sub_2.
>> All right. So like what I would do is I feel like I would parallel >> what I do.
>> And so the answer would have been um so like watch check it out fast. So if this is f_sub_2 what would this be?
This could be what a parallelogram. Oh yeah.
>> F2. F2 that be >> f_sub_2 f_sub_2.
>> If this is f_sub_1 well you know what I mean? So, you're looking for something that looks like >> Wait, this might have been the last one, man. It might have been D.
>> Hold on. Wait a minute.
>> Wait a minute.
>> Wait, wait, wait, >> wait. That's not >> That's B. That's B. Wait. No. No. It's not B. It's not B. It's not B. This is wrong. That is wrong. They're trying to tie up D.
>> Boy, >> let me explain it back again. Right. Let me explain it back again. So like you have f_sub_2 over here, I have f_sub_1 over here, right? The resultant would be okay. I would make a parallelogram like so and that will be the resultant. Are we understand that right?
>> Yes sir.
>> This is going to be f_sub_2 here and well that's going to be f1 there. So the answer was just this part over here.
So why they bring physics into this question physics?
>> They want to experiment, >> right?
>> Wait, they get through with TDD.
>> Unfortunately not.
>> No, unfortunately not. My condolences.
>> Are they could I use all the logic, you know, like imagine I'm pulling something like this and I pulling something like that.
>> So I did and I didn't get the >> Oh, I know. Seeing the the arrow for B going in the wrong direction >> like way I don't see that.
>> Yeah. Watch this going in this direction. That don't make sense.
>> I didn't I didn't clock that in the exam.
>> Watch. Like on if I pull in something like this and like this.
>> Yeah. Understand? Understand?
>> It will go like that. You know what I mean?
>> Yeah. Yeah.
>> Got to be careful. The answer is not be my friends. No, it's wrong. You >> got to right.
Yeah. Just have to divide by what? A th000,000 >> this time I get this one right 3.8 Yes sir.
>> I just point 38 but then I realize wait now I move back the >> point back and I get it.
>> Yeah.
>> So far so good. Not bad. That question kind of piss off but looking >> Nikolai we have we have a a sector over here right and we seen the angle is 60 that will be 60 over 360 which is what >> that will be 1/3 >> 1/3 >> 16 >> oh my 6 is 1 6 and 6 is 36 1 / 6 >> so where's your answer you're looking for answer with one six in of course and is 16 area of a full circle So the area of a full circle is p<unk> r square. So >> that'll be p<unk> r² >> put in.
>> Yes, sir. I just Okay. You like you see how I You see how I did that? I mean I put extra work in but Yeah. Yeah. Yeah. I got that one.
>> All right. Good. Um, talk to me.
>> Oh yeah.
Rectangle 48 m squared. CM². What is the perimeter in cm? The length is 8. So the length is 8. Um, divide by 8 to find the width.
>> What?
>> That would be six.
>> Six. And the pyramid that will be what?
12 + 16.
>> So that will be 14 + 14 which is >> 14 + 14.
>> Yeah. 6 + 8 is 14.
>> Yeah.
>> Yeah.
28.
>> Yeah. 28.
>> 28.
>> Yeah. You guys got that right?
>> Yes.
>> Oh, you guys you guys probably would have said 12 + 16.
>> Yeah.
>> Yeah. hard >> it's the same thing here >> right okay somebody ask him where did the six come from here what right they're telling us that the area of the rectangle is 48 remember area is length by width so the length by the width is equal to 48 we know that the length by the width is equal to 40 hope you understand that and they are telling us that the length is eight so the length is eight so I want to ask you a question 8 by What is 48? 8 by what is 48? 8 by 6 is 48. Right? So I get the width from that. I mean you could have just divide 48 by 8 as well and you get six, right?
That's why I get the six from because 6 by 8 has to give me back the 48 cm squared. Hopefully you understand that.
>> Yes sir.
>> Um somebody asking where the eight come from. The 8 was in the question earlier.
I kind of concerned now.
>> Yeah, people on YouTube, the eight was in the question. The eight was in the question. It tell you that the length is eight. And if the length is 8, then to get 48, you got to multiply this by six.
So the width would have be six, right?
So 6 + 8 is 14. 14 + 14 is 28, right?
Cool.
>> Okay.
>> Um I repeat, >> um five. Five. Yeah.
>> Yeah. Because like it would be 65 is equal to a half. 8 + 18 by age. Half of 26 is 13. I learned my lesson guys. It's not 26.
>> I mean it's not 36. I was saying I was saying 36 for the longest while >> so you know. So I I like I work this out halfway and I do like half do.
>> Yeah. Yeah.
This one looking out a bit different. I don't think we see this one, but it look like a >> I think it's one name.
>> Right. So, the scale on a map is 1 to 120,000.
On the map, the distance between Amy's house and a school is 8.5 cm. To find the actual actual distance.
Okay, no problem.
So, we're going to multiply both sides by 8.5. 8.5 by 12. I'm going to show you how we're going to work this, right?
Where's 12 by 8?
96 >> 96 >> 12 by eight >> 96 >> 96 >> So we have 96 in the bag, right?
>> What is half a 12?
>> Six >> six.
>> So we're already looking at 102 here, right? So it's going to be 102 followed by the the four zeros and how much kilometers you have in a how much kilometers would make up a centimeter? What? How many centimeters make up a kilometer?
You guys remember >> I believe so. Let me just verify it again though.
>> So I went from cm to to me and me to >> I put >> like I 100 then I divide by >> that's not a problem. All right. So 1 meter is how much centimeters? 1 me is how much centimeters?
>> 100.
All right. Cool.
And 1 kilometer is how much meters?
>> 1,000.
>> 1,000 m. So you can multiply 1,000 by 100 and that way you end up with something with five zeros.
>> Mhm.
>> Which is 100,000.
>> Yeah.
>> The answer is C.
>> So 10.2. Wait.
>> Wait. Nothing wrong.
>> Something wrong.
>> Wait, let me just check something. I told like I realized 120 1 2 3. I use my calculator for life support at this point is 102. Yeah, it's 1 million 20,000, right? Um, yeah. I didn't do anything wrong with Z like calculator.
>> Yeah.
>> Can like 10.2 had 10.2, right?
>> I can't remember who I have.
>> I think I put C.
>> I put I put C.
Let me get my calculator >> cuz like >> you sure >> I can't see right now.
>> Gemini says >> Gemini says as well.
>> Why DC?
>> All right. Why deadassie? Come back.
Come back fast. Yeah. So I would say >> right by 8.5 I would divide this by 100,000.
>> Yeah. 10.2. 10.2 is the answer. I was right.
>> Wow. Wonderful.
>> Right.
>> No.
But it's wonderful that you could find the answer.
>> Exactly.
>> It's wonderful. These people are working now. These people wicked. They're very wicked. Okay, next question. Let's go.
So, you need to sleep.
>> Small, small, smalls.
>> Um, to find the area >> 360 this question, they just always like bring the exact answer like and they will factor out something and it's like something here, >> but this time switch it up.
>> [ __ ] >> Yeah.
>> Yeah.
>> [ __ ] >> And they changed it from 20 27 to 29.
>> Yeah. So, it'll be 14.
>> Wickedness. Wickedness.
Huh?
>> Yeah. So, >> yeah.
>> And this going to be seven and this going to be seven.
>> Yeah.
>> Because 7 + 7 is 14. 14. You get back 29.
>> And so, care what if this radius is seven, this could be seven here as well.
>> So, we So, you end up with a a rectangle with a dimension of 14 here. That's the width. So, what would the area for the rectangle be?
>> 14 by 15.
20.
>> Yeah, I do though.
>> All right. 47 11 >> 210. Yeah.
>> And now we have to find a square.
>> So we already have a circle with a radius of seven.
>> Um R squ is 22 or 7 and 7 squar is 49. 7 into 7 is 1. 7 into 4 9 is 7. 7 by 22 is 154, >> I think. Is it 154?
>> I'm saying so. Yeah.
>> Yeah, it is. It is. It is.
>> Yeah. Yeah. Yeah.
>> So, you know, sir, you know, I just guess this answer.
>> I use common sense. I was like, wait more.
>> So, here how I do it, right? When I saw when I saw the two one, I know it's not A and I know it's not B. So, it's either C or D. And I know when I do the circle, it had to be more than C. So, I chose D.
>> Exactly. Yeah, >> that's good reason. That's good reason.
>> But they're sneaky boy. Sneaky CX is let me tell you something. Sir, let me tell you something. You have my heart palpitating right now to see how much I get wrong.
>> Yeah. Yeah.
>> Let me keep going. Let me keep going.
Then >> number 39 watching.
>> I hope you have so far.
I get like four.
>> Same. I have like two. I I get six so far.
>> When we um finish, I would just run through all the solutions. Make sure the solutions correct cuz you know like right now, >> yeah, I would just run through the question everything and make sure to be correct.
>> Um since 37 the area of a rectangle is 40. Um if the length is Oh, we do questions like this before. So remember area is length by width. So the length increasing by four so be 4 L and the width is halved. So it's just going to be four times a half which is 2 LW which is two times the area. So if the area was 40 then the new area will be 2x4 which is >> somebody sent this question actually to this morning it was >> same somebody come up to me and was like >> that's how I remember this.
of course.
>> Yeah, sir.
>> I remember it from your class in the group chat this morning.
>> Four from your class.
>> Mhm.
>> That's good. Like like with two times the area and you just multiply by two.
>> Yeah. Yeah. Yeah.
>> That's good.
>> I know exactly what you did. But I reached like I I reached one mark short.
>> Ah. So, and just to to check over, I just plug in random numbers as the length and width.
>> Yeah, me too. I plug in 10.
>> I plug in five and seven.
>> Five and seven.
>> Yeah, >> I do five and eight.
>> It's like to see if it would be twice.
>> Yeah.
>> Message.
Yeah.
Mrs. M's not feeling well. Uhoh.
Yeah, >> take her to the doctor, sir.
>> I'll have I have to.
All right. Um 37 C. Are you okay with that?
>> Of course.
>> Yes, sir.
>> Um 38. Dina drove her car at 58 km/h for 6 hours, then increase her speed by 17 km/h to ensure that she reached her destination in another 1 and a half hours. Her average speed in kilm for the entire journey was all right. Let me take this question in bite-sized pieces.
So, she drove a car at 58 km/h for 6 hours.
Okay, here what right immediately I could weigh out some answers. If she's increasing her speed, do you think the average would be less than 58 or more than 58?
>> More.
>> More.
Could I just think about it like that?
Wow.
>> Yeah. I don't think the answer is 60.
>> I think it's 60. I think it's 61.4. But let me use it anyway.
>> I put the >> I like I'd find the total distance >> and divide by the time, >> right? to ensure wait give a second. All right. All right. So here what 58x 6 that would give me the distance like Aen said 58 by 6 that's 348 that's 348 km she cover here >> and if she increase her speed by 17 that's going to be 58 + 7 which is 56 775 km/h and verify that my calculator 58 + 17 75 and um they're saying that she reached the destination in another one and a half hours. So I multiply this by 1.5 and that'll be 112.5.
Okay. Um so that'll be 112.5 plus 348.
So all together that'll be 460.5 and her average >> by 7.5 I believe.
>> Yeah. Total.
>> Yeah. 61.4.
Tell you know like like you could just look at the question and figure it out like because here what if you if she travel at 15 km/h and then she increase her speed would the average go up or the average go down?
>> So you know what I do right I was doing what you had now do but like halfway but then I think about the common sense way halfway when I was doing it.
>> That's good.
>> So I just put on the right you put on B.
No, >> wait. But >> I had put C sir. At first I had put A, right? But then I was like, no, if it's increasing, then I have to be more. And I had leave this question last because I had a bunch of um working on my paper. I was like, it's not adding up. And the division is too long for me and I have to like hurry up through the things to finish the paper. So I say I'mma come back to it. So I come back to it last minute. It was the last question I worked on >> and I was like, "Okay, >> let me just use process of elimination.
It can't be A, it can't be B. So, it's between C and D. I'm going to say C."
And I put C down and then she say pencils down. And I was like, I hope it's correct.
>> It is what it is. It is what it is.
>> Serious.
I second guess what's up. Well, you think about it like it went up from 58 to like 75. 58 to 75. The answer like 60.
>> Can I go a little more? I say 61.4.
>> Mhm.
>> Um >> I believe I put that answer >> the answer is >> wait real when I look at this question I was like huh nominal. So I don't I don't know.
>> I don't know. I was like what >> like how I do this right?
>> 30 students recorded the colors of their eyes choosing from the colors brown, blue, green, hazel and black. The measurement scale used in this scenario is the ratio make don't make any sense.
Ordinal though interval no like okay nominal is like a small it's like a like a small scale. That's what nominal means. All right. It's just 30 students and it's just a couple colors. It's a small scale scenario. Understand? It's like a small scale scenario. That's what nominal means. Nominal means small scale.
>> Yeah.
>> Small small.
>> No, it's not ratio. Ratio don't make any sense, guys. You wouldn't use a ratio scenario. That don't make sense. Okay.
Like when we talk about the scale of like the measurement scale is like a large scale, like medium scale, you know. No, we don't just mean small. I was like I was thinking like you know they putting their eyes together like the color eyes together. So I was like okay you could do it in a ratio and I didn't know what nominal was. So I was like it can't be normal. I was thinking I didn't know what I didn't know anything.
>> Yeah. I thought it was like that skipping numbers. I was like ordinal.
>> Exactly. So I do I take my pencil.
>> I put same >> I put a ratio.
>> I put C. I say it was not ratio and it was not ordinal. It had to be between interval >> or nominal.
>> I put interval.
>> What?
If we talking about the scale of measuring something, right? Talking about the scale. Why is the fake Apple Pencil not working? The fake Apple Pencil dead too. What?
>> That's a sign. That's a sign.
>> Use your finger now. Cassidy, you finger.
>> Oh my god.
>> Sir, you remember the video when my my Apple Pencil died? I had to use my finger.
>> Sir, I saw a video in the chat explaining um number 60 and my Apple Pencil died. I had to use my finger.
>> You had to use it for >> Yeah. So guys, ratio don't make any sense. ratio is uh you're talking about the scale of the the scale of the scenario like how big or small it was.
Ordinal don't make sense. Ordinal is just like quartile is like a rank cuz like the fifth the fourth the fifth half mark that's what ordinal means. Interval is like um like from here to here to here like like the semi interquartile range like interval. Oh god, the phone fall down. Or like you know like um when you're doing um statistics you have like different intervals like 41 to 60. You know what I mean?
>> Yeah, that's interval. The answer was no.
>> Uh 40 is that repeat?
>> Yes.
Yes.
>> Yeah. Yeah, it's 166 was the um interval thingy, right?
Um 39 was nominal.
>> Yeah. Yeah. Yeah.
>> Yeah.
Um 40 was 166. Watch.
>> Yeah.
>> Uh 166.
>> Good afternoon, sir.
>> Good afternoon, Virginia. Virginia, just here for vibes.
>> Yes, sir.
>> What was the answer? It's on repeat as well. What was the answer?
>> Yeah. 37.5.
>> Food. What?
All right. Um, if exactly 28 students pass the test, then the pass mark is most likely to exactly 28.
>> I put 23.
>> It's 23.
>> So like 28, buddy.
>> So like every block is four, right? So I got to go up to seven blocks.
>> So that's like that's give or take. Give or take.
That's 23.
>> Yeah.
>> I see now. I was like 23.
>> Sir Reisha asks if you send in this in the chat.
>> Yeah. Yeah. I was send this in the chat.
>> Okay. Thank you.
>> Um if I repeat was the answer.
>> I think I was question 42.
>> Wait. You asking you asking why the answer for 42 is a >> no asking what is the answer? Oh, 42 is aim.
All right. Um, 43 was D, right? This I repeat a respondant from a ethnic group.
Ah, no, this not repeat. This is like conditional probability.
>> New answer is a new one.
>> It's a new real sneaky boy. We >> real sneaky sneaky. All right. So, here what they're saying. A respondent from ethnic group P. So, how much people have in P?
>> 60. 16.
>> And um way >> what is the probability that that he has a negative attitude towards mass?
>> No.
>> So at first I put at first I put A and then when I check it back I put C. Uh, thank God. Damn good.
>> Because I put I put I put 24 on.
>> Oh, no.
>> My glasses was dirty. That's my excuse.
>> I believe you. I believe you. Yeah, >> me too. Me too. I believe you. them things happen. Look >> like >> people keep saying 42 is wrong, but I don't see how 42 wrong. Like >> you have to stay >> so exactly wait they're saying exactly 28 students pass the test. Um then the pass mark is most likely >> so 28 students pass the test, right?
So if it's 28 students pass the test then okay I see I see why it could be wrong. Um if 28 students pass the test right. Okay imagine we have 200 people all together right and if 28 students but that 28 students could be anywhere.
>> Yeah.
>> So you know what they do they minus the 60 from the 28 where it lie on the thing. No, no, no. Weird line.
>> No, like you could it could also do this. You can say 200 minus 28 and that'll give you one um that'll be 172 and that's probably what it do. They probably look like 172 over here. But that's like real high and then they'll probably say like like 46.
H give me a second.
>> So I swear if this thing wrong, I going to cry.
>> Me too. I go cry so fast >> because I literally was like I remember sir say we have to go on the graph for this so let me go on the graph >> n it is see it is see this sneaky question let me go over again right it let me go it over again cuz like I was 23 kind of low yeah so I'll go it over again they're saying exactly 28 students pass the test So 28 out of what?
>> 200 >> 200 >> right? So it's 200 minus 28 and so that means 170 students what the 172 170 172 students do what? What did they do?
>> They fail.
>> If 28 >> they fail, right?
>> Yeah, they fail. So then you go on the graph, you look for 172. Um 172 might probably be somewhere over here per say that looking like approximately what >> about 46.
>> Yeah.
Wait.
All right. Five wrong now.
>> I don't even Okay, let me try to explain it back again.
>> Let me try to explain it back again. So, if exactly 28 students pass the test, then how much people fail?
>> 172.
>> 172 people fail. 170 people fail. So, like you had to go on the graph, look at 172.
And everybody, everybody down here, everybody here, what they do?
>> They pass.
>> No, they fail. They failed.
And the 28 people over here, they watch >> they pass.
>> They pass. So yeah, it's a tricky question.
>> This is crazy.
>> This is This is viol.
>> It's a tricky question.
>> Yeah. Thank you for the people on YouTube that that suggested it was wrong. The answer looked kind of wrong.
At 23 months, >> this make more sense. That makes sense.
So >> yeah. So like the 28 people over here, this is the 28 people that um that actually pass.
>> Yeah.
Okay.
>> Um which of the following diagrams best illustrates a function? The answer was B, right?
>> Yes.
>> As a one to one. Mhm. Is a repeat as well. What's the answer?
Uh >> D 4x + 5.
>> They changed the order of the >> options.
>> Maximum point. Maximum point like two4.
>> Yeah. Kick.
>> Wait wait wait wait say going too fast.
>> Um 43 D 44 C 45 B 46 D.
Okay.
>> Um 47 that is going to be 24.
>> Mhm.
>> Right.
>> Yeah.
>> All right. This repeats that was 2 by - 3^ 2 - 1 - 3 square is 9 by 2 is 18. 18 - 70.
>> 48 C.
>> Of course.
>> All right. 48 C.
Does that repeat? Oh, no. No, no, no.
They change it up slightly. If the line if the line segment is extended at what point is the line segment expected to intercept the vertical axis?
>> Dell key boy. Wow.
Yeah.
>> Correct. Correct.
>> Me too. I correct. I the exact same thing sir do I was like use your sense.
I take my ruler and I draw a line.
>> I draw my line.
>> High five. High five.
>> I use my finger.
>> I >> Yeah, I don't even know.
>> I liking some of these results, you know, but some of them >> some of them, >> right?
>> Yeah. What? Right.
>> A lot of people wait a lot of people just memorize the answers, right? And a lot of people like, okay, with this question, um, it typically bring it a bit different. And most of some people would have put like B or C or D or something but n the answer is A. So kind of like a different question. Yeah. Extend it. And it cuts at 0 0.
>> Mhm.
>> Yeah. Yes sir.
>> Of course.
>> Right. 49A.
Uh 50. The equation of the perpendicular bis sector of AB. Let me show you how to do this fast. Right. Um you could find the gradient of this line and the gradient of the perpendicular bis sector would just be the negative reciprocal.
>> So to find the gradient that just rise over run.
>> So be two >> two over four.
>> Yeah. I got half and then I change it.
That be minus two.
>> Yeah.
>> So that is four. This look like a No, this look like another word. Fix that.
So looking at the other um so forward one second buddy.
I need sleep.
>> All right. As you can see, guys, we're rising up by two and we running across by four. So the rise is two, the run is four. So 2 over four is what?
>> Right? I want you to flip that. If you flip overus and you change the sign, it's going to be minus2.
So let me run it back again is rise over run. So you're rising by two. So the rise is two and the run you're running across four. So 2 over 4 is a half, right? What you want to do since the line they're talking about is the perpendicular bis sector, it's going to have a gradient that's a negative reciprocal. So you flip this 2 over one, change the sign -2. So it's going to be um D looking at the correct answer.
>> Yes. Right.
>> Yes sir.
>> Yes sir.
>> So when I see the 10 I was contemplating you know >> the off the t off but then when I find the gradient I was like oh okay >> that's the only one that makes sense.
That's the only one that makes sense.
>> Yeah.
>> Right. So again like gradient is you see what like here's the problem.
Right.
The night before the exams I just want to do 10hour marathons and 12 hour marathons running on and the next day I can't function. That is the problem.
That is the problem. That is the problem. That is the problem right there.
>> That's the issue.
>> What are the solutions operating issues?
Sleep is important. Sleep is important.
Sleep is a very important thing.
Um which of the following >> liking so many things.
>> Oh just bring this question in a different way. Just bring this question.
>> I realize that >> it was a because when I saw when I saw it was in brackets I was like what?
>> Yeah.
>> But it was a >> they just bring this question all the time. It just look like this.
>> Yeah.
>> Yeah. Yeah.
>> You had to add three.
You have to add three, >> right? When you add three >> that it's okay to go from to go from to map the elements in X to Y, you have to add three to X. So Y is equal to X + 3.
So it was 51.
>> 518.
>> Yeah. Yeah.
>> Um, which of the following velocity time graph represents John's motion along the straight line? Let me read it fast.
>> D.
>> Um, waiter. For the first 10 seconds, John starts from rest and runs with uniform acceleration.
If it's acceleration, then we talking about like this, right?
>> Yeah. We're going up.
And it's saying he starts from rest. So it have to look like this. And this be zero and this be 10. So we looking for anything >> looking like B >> cuz like watch in the first 10 seconds he starts from rest. So 0 0 and runs with uniform acceleration. And he then runs at a constant speed cuz at constant speed no acceleration. Um and he did that for next 10 seconds. And so that would take us to 20. And he slowly decreases his speed to arrive at his destination within um the final 10 seconds. So at 30, if he reaches his destination, he will stop. B.
>> So I only look at >> I look at and say that was the only grab that was looking proper.
>> Yeah.
>> So for one moment was looking at D. But when I say he start well he start from rest >> and and think about it logically too right typically when time is zero are you moving yet?
>> No >> n >> ah so like you start from rest typically unless you're dealing with a fixed point question like an advance.
Um so it's saying e I think it's cosine e to b over >> this um which are the following ratio.
>> This is an adm question.
>> I guessed I guess >> like at a point oh here when I was doing when I was doing one of the papers with you guys I was telling that sin 30 would be equal to cosine 60 or something like that.
>> Yes.
>> This has to do with complimentary angles. Anytime the angles add up to 90, they're equal. So here what I saying >> um the answer that makes sense here all these wrongs. These are wrong immediately. Um it will be sin 90 minus d.
>> Oh okay great greatness.
>> I'll take >> like explain something right consider a was let me just say a was 60° right?
90 - 60 is 30. What would what would 60 and 30 add up to?
>> 90, right? Once the angles add up to 90, it's correct.
>> Yeah. So, the answer is 53A.
Complimentary angles are equal.
Didn't think this would have come.
>> Sorry.
>> Don't think this would have come. Yeah.
>> Oh, I thought about it was like um because you use the these rules and a right angle triangle. So one of the sides was already 90 and then the other one have to be 90 minus the angle A and we already had co so it had to be sign.
So that's how I got that answer.
>> I don't know.
>> That's a creative way to think about it.
>> That is a creative way to think about. I like that your real thing there cuz like if I were to draw a triangle um and I tell you that cosine A is equal to B / C, right?
Um let's say let's say for a second that this is a right let's say for a second that's a um we know that cosine theta well is equal to a / h. So then well this is the hypotenuse this will be the adjacent that's going to be opposite.
The other angle of course would be what?
What would the other angle be?
>> 90us the 8.
>> Yeah it be 90.
Well you already take away 90 from 180.
So what angle I have remaining? 180 - 90 is what?
>> 90 >> 90. So that'll be 90 minus a. And if I using this angle to label everything, this will be the hypotenuse adjacent for the opposite.
So using these two again, that's going to be over h. So it's going to be sin 90 minus a is equal to over h. It's really creative.
Yeah, you're bad. You're bad. I rate you for that. Um, >> yes.
>> Right. 53A.
Uh 54. In which of the following polygons are the sum of the measures of the interior angles equal to Z. Repeat?
You know this one.
>> Repeat.
>> Quadrilateral, right?
>> Quadrilateral.
>> Quadrilateral.
>> You don't know. You don't know. You don't know.
>> Nice. Nice. Nice.
>> The exterior angles always add up to 360. And the well for a quadrilateral all the angles is 90. So if you have four 90 degree angles, I would give you a 360 as well.
>> Yeah. Yeah.
Um 55. Which what sequence of transformations will map WXYZ image >> is refction enlargement?
>> Only one of them had reflection.
>> Yeah.
>> Is a reflection first.
>> Uhhuh.
>> And then then it's a >> scale factor.
>> Scale factor of a half.
>> Yeah.
B.
>> Yeah. B is the only one with reflection in them.
>> Exactly. Okay. So maybe >> here's a reflection on the y ais, right?
Check. And then is a enlargement with a scale factor of a half cuz again two times smaller.
>> Mhm. Yeah.
>> Yeah. So 35D.
>> Mhm.
>> Right. Sorry. We love this question. We love this question. Too bad.
>> The answer is 3.5.
>> So this was my redemption here now.
>> Yes.
>> Redemption. Redemption. 21.
>> Yeah.
>> Same things but way >> nice.
>> Yes.
>> Yeah. Of course.
>> Yeah. Got to use of course cuz >> multiply by 10 through 10 >> I repeat customer with this one >> P 90 question >> if it was originally going at 45 then to go 135 Five.
Yeah. I have to change its course by 90°.
Yeah. All right. Last question. S this one. S like Hey, this is where the circle term went. This is where the circle term went.
>> So, I guess the last question.
>> I was so happy when I saw this question.
Okay.
>> Go back to a second.
>> Oh, okay. Okay.
I think I think I put a can't remember this question.
>> 130 I just trying to do remember why do Yeah. Yeah. Yeah. Yeah. Yeah.
I just minus >> me too. But I remember >> the minus was for proof.
>> Yeah. I just want to make sure. I was just iffy.
>> All right. We go to 16.
>> All right. Yeah. Sorry. Read from now.
>> Item 60 refers to the following diagram which shows a circle with a center O and the points A, B and C are on its circumference. The line ECF is a tangent to the circle at C and angle ACB and angle FCB are 34 and 74° respectively. Which of the following options shows the correct values for P and Q? Right off the bat, people, the angle at the center is twice the angle at the circumference. If 34 is at the circumference, then 34 by 2 would give me P. And 2 by 34 is 68.
Then y'all really have to look for this one. You see that there? You see that little 74? That's a tangent. And then you see AC, that's a triangle. The angle formed between a tangent and a triangle is equal to the interior opposite. So, and it's not a little tiny part. No, it's that whole angle. Right? So, now you see that triangle A O B that's a isosles triangle. All we got to do right now is subtract 68 from 180 and divide it by two. When you do that, you'll get 112 and 112 / 2 would give you 56.
So that means um a and b is 56. Now 74 minus 56 will be that little sliver there. And 74 minus 56 is 18.
>> 18.
>> 18. It's not 18.
>> No, it's 18. It's 18.
>> Yeah.
>> Sir, stop doing my stop doing that.
>> Exactly. Like bro, it's just Sorry.
Sorry. Sorry man. Sleepy. Many babe.
Greatness.
>> Greatness.
>> I I find I do I find should I do more these circle in the questions than the money questions?
>> Yeah, I hear that money question.
>> I love those money questions, guys.
Please.
>> N.
>> So, you don't think six wrong is bad?
Like in total?
>> No.
At least at least in the 50s, you know, >> I get eight wrong. So, you know, >> I pretty sure in the 40s or something was awful.
>> All right. I can't remember my answers, so I just going off. I remember. I think I in the 40s. I'm not sure.
>> Yeah, I in the 40s definitely.
>> Right. All right. So, let me try to reexplain. Let me go over the paper.
Make sure cuz guys, all you know, I sleep, right? Uh I want you guys help me. We're going to go over the paper and make sure these answers are correct cuz I don't want to be putting out wrong answers, right? Don't want to be doing that. Next thing people say, Mark lives a >> you.
>> We got you, sir. That's true. We got you.
>> Somebody say they get 65. 65 for >> 65.
>> You made five questions and answer them yourself.
>> He put He create E.
>> He must be CXE. He must be CX.
>> So, sir, he put name and everything.
That was extra points lesson.
>> Candidate number.
>> So here, let me just let me just go through questions.
>> Let me just go through the questions and make sure each one is correct, right? So um I trust Sara. This was a good explanation, right? Angles at the circumference is going to be half the angle at the center. So if that's 34, this would have to be 68. Um this is our isoclesles triangle. So 68 from 180 is 112. 112 divided by 2 is 56. 56. Good.
Um the angle between the um the angle between the tangent and the side of the triangle is equal to the interior opposite angle. So this is 74. This is 74 as well. So that's going to be 56 from 74. And that's going to give you 18. So Q was in fact 18 and P was 68. So this is correct, right? Are you okay with that?
>> Yes, sir.
>> All right. So, 60B, right? 60B.
Somebody Wait, no, I should write it here. So, 60. Give me a second. Um, should create a new note or something.
Notebook.
I I really I really want to make sure these these these um solutions are correct.
When you guys become adults, I really hope you stay humble and like you understand that it could be wrong. You know what I mean? I really hope >> it'll be like >> be like and you know Caribbean parents could be like like you know they know it wrong but it wouldn't sit around. You know what I mean?
>> Yes sir.
>> Yeah.
>> Yeah.
So yeah, let me start from one and go all the way down. Let me go all the way down. Right. So question one that was without a doubt that was D cuz - 3 2 is 9 and -2 2 is 4. 9 + 4 is >> 13. 13.
>> All right. Without a doubt that is D.
Question two. Um when 0.45 45 it's written as a common fraction in its simplest form. Um we know that's going to be 45 over 100 45 over 100 that is without a doubt 9 over 20. So that's going to be 2 a right. Question three you have to add 2/3 to our third to get two. So the answer is without a doubt B for short.
Uh question four we have 235 by 48.7 is equal to that and then they shift the decimal place. But logically a little less than half of 23 is going to be like like 12 or something around that range. So the answer is E.
So four is definitely E. Correct. Are you sure about that? Um five. Now based on the information in the table, umpires are paid a flat fee off. Guys, as you know, they're getting a fee just for what? Just for what?
>> For showing up.
for appearing >> right >> just for showing up.
>> Just for showing up. Them kind of useless now them getting them just for showing up you know just for showing up.
So here what would that be the first match or before the first match?
Sarah, come help me here. Yeah, Sarah, would that be would that be for the first match or before the first match?
Flat FIFA 5 >> that um that would be before the match.
>> Exactly before the match.
>> So we actually have to backtrack a bit.
Right. So if 3 is 20 250 notice that it's going up by 250. So you just backtrack.
So 1500 that is 100% correct. I can't see that being wrong. Um so five is without a doubt C. All right. Six.
Umpire A officiates at 10 games while umpire B officiates at six. So umpire A is going to have 10 games. So if you run 10 games, it amounts to how much money earned it?
>> $4,000 4,000.
>> 4,000, right? So it's 4,000. And if you officiate six games, how much you going to get?
>> 3,000. 3,000.
>> Right. So that's going to be 4,000. I see buddy. It's going to be 4,000 to 3,000. If you divide through by a,000, that's definitely going to be what?
>> 4 and three. Four to three.
>> Four to three. Right. Four to three.
>> Yes, sir.
>> Here. Yes. I'll check it for you on WhatsApp. Right. That'll be six B.
Everybody okay with with the answers so far? Right.
>> Yes, sir.
Um they they want me to find the number of possible subsets of set M. We have three elements in M. So that's going to be 2 to the^ 3. That's eight. That is definitely correct. 70 um 8 M the number in M intersect N complement.
So in n in n we have elements p and q and I saying okay so if it's n complement it's going to be everything but p and q so what are the what are everything other than p and q >> r >> s talk to me >> r >> everything other than p and q >> rs r >> rs Right. And what we have in M? In M we have >> R, >> P, Q and R. So what do they have in common? What do they have in common?
>> They have R in common.
>> Right. So the intersection would just have one element. The intersection would just have one element. So this has to be correct. 8 B. 8 B. That has to be correct.
Right.
You guys put that right. One. One.
>> Yes sir.
>> Yes sir. Yes sir.
>> Okay. Good. Good.
Which of the following statements about sets M and N is true? So if I add up everything in M and N, that's just M.
That's correct cuz watch M is PQR and N is PQ. If I add it up, that just be PQR, which is M. So that without a doubt is correct. 9 is 9 is definitely P.
um 10 empty set that's going to be Q intersect R because uneven numbers have nothing in common. So 10 is going to be D for sure. For sure.
Um since it gave us only you add it up take away from 36 + 48 that's going to be 84.
84 from 100 is going to be 16. So 11 was definitely B right. I find like you helping me you know I kind of I going over this by myself. I need to borrow your brain power.
>> Sir I watch >> um how many to help?
>> No problem.
How many students play tennis but not chess? If it's not chess then it is tennis alone. As you could see only four people played tennis alone. Paul and Rayma actually played tennis and chess.
So the answer for 12 was definitely C.
Was definitely C. So that's going to be 12 C, right? 12 C for sure.
Then 13.
A refrigerator cost $1850. Um 5% sales tax on that is added. If you're adding sales tax, it has to be more than 1850.
So it's without a doubt 1942.50. All the other answers are less than 1850. So 13 is without a doubt D. Definitely D. Um 14. We went from $250 EC to 25. So we multiply by 10. So you'll have to multiply US $1 by 10. So 14 is definitely B, right? So 14 is definitely B.
Uh 15. Now for every 100 in sales or a part thereof, a salesman is paid $10 as a commission.
So Cassidy, if a salesman Cassidy, if a salesman get a sale for $105, how much you going to get?
>> You will get $20.
>> $20 because they said part, they said part >> there off part there.
>> So even if you have like a part, $10 you're going to get. So we got um 10.2.
So 10 by 10 is 100 and the part they off is a 10. So that's going to be 110. So 15 is without a doubt D.
Um 16 5 cents on 450,000. Yes, that is 22,500.
So 16 is definitely B.
Um 17 7 cents by 180 cuz there were 180 18,000.
Um we're getting 126. So that's definitely D. So 17 D 18.
So his basic rate would have been 600 divided by 40 which is 15. I'm going to check it on my calculator. Again, I really don't want any of these answers to be incorrect for 15. Yeah. Um 1.5 * that is 22.5. We did that correct. And the excess amount is going to be 802.5 - 600 which is going to be - 600 that's going to be 202.5 divided by 22.5. Yeah, that is 9. So 18 is correct.
18 is definitely a um 19.
The simple interest on a sum of money invested at 5% perom for 3 years was 90.
Um, that's going to be 9,000 divided by 50. I'm checking on my calculator to make sure.
Yep, that is 619 is definitely C at 20 as a sale. Jack bought a bat for $36. The sale included a 10% discount.
So, he paid with the 10. He said he paid he only paid 90%. Cuz the discount was already factored in. So, 1% is 4 10 multip.
So 20 is correct as well. 20 is D.
Um Nikolai there.
>> Yes sir.
>> Nikolai I just I just like making sure the answer is correct. So you go use this answer key to check if your answer is correct.
Um >> get I didn't get six right. I got seven because I saw on >> 67 >> seven mention.
No, I guess seven wrong because I saw there was one question on top. I didn't I came in kind of late now. So from what I saw I I got six.
>> Which question was that?
>> Could you go back up please?
>> The umpire one, >> I believe. So yeah, when it was I put 250 because I thought that was the difference.
>> No, no. They want us to figure out the the the flat fee the umpire receiver. That will be for the the zero game. They didn't they didn't even they didn't even play a game yet. They didn't even officiate a game yet. They just come. So that'll be like the zero game.
The the zero game. Yeah. Um right. Cool.
21 3x2 is 6 x^ 5. That is without a doubt a >> sir. Repeat.
>> Um 22. We had to divide through by two.
So it's going to be two is less than x is less than equal to three. The answer is definitely >> a >> yes sir.
>> Definitely.
>> Um this we definitely D. Definitely D because it's going to it's going to >> it's going to stretch six more times. So 30 by 6 is 180. The closest answer is 179.8. That's definitely the Yes sir. Um this we fed up with this question. The answer is definitely X plus 5 >> because if John had X and he gets five from Max, we don't care how much Max have. The point is John getting five marble. So that'll be X + 5. X + 5 which is a um 25.
The answer is 2 a + b because 2x 3 is 6.
6 + 6 is 12. Right? Then 2x 2 is 4. 4 + 5 is 9. That's correct. So 25 was definitely 25 was definitely C.
Um 26.
If a is equal to 3, then b would have to be 2. So a is 3, b is 2. So 3 squ is 9.
Um 9 - 2 just 9 that's which is 4. 9 - 4 is 5. So the answer is definitely c. 26 c.
27. And we're going to multiply every single thing here by three. The answer is without a doubt a um yeah, not looking like it. Uh 28 58 are 40. 40 - 42 is definitely minus 2. So that's going to be 28 B.
Um 29 uh P minus Q. That is 3 - - 2 - - 2 is + 2. 3 + 2 is 5. 7 - 5 is 2. So 5 2 the answer is definitely 29 C.
30. Now 30 was a nice question. Um this is the answer here. The resultant the resultant vector we're looking at is really this over here formed by the diagonal for the parallelogram. So that would be f_sub_1 f_sub_2 there. And the resultant vector had to be in that direction. So B was a um a trap. The answer was without a doubt 30D.
30D um >> 31 >> 1,000 mm make up one meter. So you by,000.
Say that again. You got 31 wrong.
>> No, no, no. I was going to say the answer which was B. I was just helping you make sure. Yeah, the answer is because good good um because 3800 divided by 1,000 that is 3.8 and I am not going to trust myself. I'm going to plug it into my calculator just to make sure.
Yeah, 3.8. Cool. We have a sector over here. The angle is 60° which means it's 16th of the whole whole circle. So, it's going to be 16. And the area for the full circle is p<unk> r^ 2. So 16 p<unk> r^ 2 which is definitely a. So 32 is definitely a um 33. They give us the area. They give us the length. So we had to figure out what by 8 will give back 48. So that's six. So that be 6 + 8 is 14. 14 + 6 is 20. 20 + 8 is 28. Right. So 33 C.
>> Yes sir. Um that's definitely correct.
34 they give us the area. We know area of a trapezium is a half a plus b by height. A is 8, b is 18. So that'll be 26. Half of 26 is 13. Um 65 divided by 13 that is 5. So 34 c right. Um 35. Now the scale on her map is 1 to 120,000 and she measured 8.5 cm on her map. So she'll multiply everything by 8.5 8.5.
We have 120,000 here.
1201 23 by 8.5.
That is 1,20,000.
Yeah, we have that. And 100,000 cm make up 1 kilometer. So I divide by 100,000.
Yeah. 10.2. 35 is definitely a 35 is a >> Nol. You put that.
>> No, I put the 102 sir.
>> Oh yeah. You sure you understand that?
>> Yes. Thanks.
>> Like god forbid, God forbid you guys have to write back the exams, but if you do, this is important. Like you don't understand.
Right. Um had to charge my phone day.
All right, let me continue.
25 was a without a doubt. Um 36.
Uh so like we had 29 29 - 15. Oh yeah, I using my calculator, right? Don't worry, these answers will be wrong.
14 14 / 2 is 7. So seven is going to then be the radius.
Um yeah right. So seven is without a doubt the radius.
Cool. Now we to find total area. So if this is seven, this is seven. This is going to be 14 and this is going to be 15. 14 by 15 is definitely 210. So this is 210.
Um and now we have two semicircles.
These this would make a full circle. and a circle with a radius of 7. So that's going to be pi r 2. Pi is 22 over 7. r is 7 squar. Um so you end up with 22x 7 which is 154. Let me verify 22x 7. Yeah.
And so yeah I have to add 154 to the 210.
Yeah. 364. So 36D.
36D.
All right. Um that's correct.
36 is D.
So yeah, is it >> um 37 the area of a rectangle is 40. The length is multiplied by 4. So it's going to be 4 L and the width is going to be half. So that's half W. So 4 by a half is 2. That's going to be 2 * length by width. Length by width is actually area.
So the area is going to be multiplied by 2. So 40 by 2 is 80. So 37 C.
>> So I taking a screenshot of these answers.
>> No problem.
After after like a I put the answers on I will make like a nice document.
Um >> I'm not a problem. So in this in this question the proper way to do it is to find the total distance and divide it by the total time taken. So that would really be 58 by 6. 58 by 6 that would be 348 km. And then she increases speed by 17. So 58 + 17 that's going to be 75.
Um and she traveled at this speed for another 1 and 1/2 hours. So that's 1.5.
So 75 by 1.5 that is 112.5.
Um so you're going to get you're going to get 460.5 and what's the total time Nikolai?
>> Well it travel 6 hours and one and a half. They would just be 7 and a half or 7.5 >> and you should see immediately Nikolai.
>> All right. Well, never mind. But yeah, 465 460.5 over 7.5. That will give you the 61.4. That will give you the 61.4.
So that is definitely the correct answer. It's definitely 38D.
It's definitely 38B. Um 39. No.
>> 30 students recorded the colors of their eyes. Okay. Since it was a small scale, it was a nominal. Nominal just means like a small scale. So 39D. It was 39D.
All right. 40.
40 is going to be this is a easy one.
How many students scored at most 40 45 marks? What does at most mean? At most just means less than equal to right. You know that Nikolai say >> at most at the 45 and less.
>> Exactly. Exactly. So what we're going to do is we're going to go where you're going to go look for 45. 45 is right here.
That's that's 166 C. And these would represent the students here that um scored less than or equal to 45.
Right. Um Kieran 31 and 32. 31 was B and 32 was A. 31 was B and 32 was A. Right?
So the answer for 40 was without a doubt C. 40 C.
um 41 the median mark scored by the 200 students. This is just going to be the half mark. So like you're going to find half of 200 which is 100 and that's like around 37.5. So the answer is 37.5 41B that's correct and this was a kind of tricky question because and I did it wrong the first time I did it.
Apologize. So, Nikolai, they're saying exactly.
>> Nah, it's it's not 170. It's not 170.
It's not 170.
>> Um, let me just verify that.
No, that's not 170. That's not 170. Mim me. That's not 170. Right. Because like that can't be 170 like cuz Okay, let let me find the same question but like a better graph and you'll see it can't be that. Look the same question over here. The same question over here, right? Look at this guys. This is the exact same question.
Exact same question. 45 is here.
What I look like if every big block is four then this would be 164 and this would be 166 >> is definitely 166. It can't be 170. You know where 170 would I be? This is 164.
This is 168. 170 would be over here.
This is where 170 is. Cannot be 170. I'm sure about that. I could bet my life on that. It's probably 170.
Anybody any other 170?
Nah. No.
>> Yeah. I don't know who say somebody say some other YouTuber say 170. I don't know how. Nah, I don't know how they getting 170. Probably like the bad copy or something. But this question repeats all the time, right?
Yeah.
Is is definitely 166, right? Not 170.
Don't put 170. That's not That's not correct. Um 42. So, Nikolai, if exactly 28 students pass the test, how many students fail the test?
46.
>> Oh, no, no, no.
>> No, >> I don't answer.
>> Correct.
So here what I say here what I say this was a tricky question so to speak if 28 students pass the test then that would be like that would be like this upper upper threshold over here. So for us to actually find the answer what you need to do now you need to find how much students failed the test which is everybody over here and that would give you answer. So how many students failed 172 students failed. So now Nikolai, I'm going to go on which axis for 172 students failed. I'm going to go on which axis now?
>> The y axis, >> right? 172.
Um 172, right? That looking somewhere I looking like somewhere over here.
Yes. I'm going look at the good graph over here. So 172. It's going to be 164 168 172.
This is a nice question though.
164 168.
Anytime I see a hard question, don't don't like don't hate the question. Just think of it like a learning experience.
164 168 right it's going to be here Nikolai what I looking like uh one looking like 46 yeah that's 46 so the answer the answer for 42 was 46 Yeah.
>> Sorry. So now with that question, >> this question >> Yeah, that question was >> that question was um tricky. It's tricky >> right but like you had to understand if you read off 28 from the graph what you are doing is you are finding the 28 students. Okay, Cassidy, if you read off 28 from the graph, you are finding the mark that that like the 28 student got. That's what you >> Yeah, >> but that that is not what the question talking about. I'll go over it again, Nikolai.
>> If you go and measure 28 like what we did initially, which is very wrong. I don't know how why I do that. Um, that is not going to be correct because that would tell you the mark the what person got.
That would tell you the mark the the 28th person got. Got.
>> Yeah. You understand, Nikolai? This will tell you the mark the 28th person got.
But is that what we want to figure out?
>> No, sir.
>> No. We want to want to figure out what was the pass mark. So, if 28 students pass the test, then 172 failed. So we could we could actually see that over here.
So here what Nikolai the 170 second person they would have gotten what mark?
>> They would have repeat.
Okay. The 172nd person would have gotten what mark?
>> Oh 46.
>> Yeah. So 46. So everybody after the 46 they would have what? Pass.
>> Exactly. So that's why 46 is the pass mark. You understand?
>> Yes sir.
>> Tricky question.
42 C. Um 43 they're telling us see does that repeat? Um what we know how to do it. It's just four uh four. Gosh. Why this thing g so much trouble?
The equipment does know when to give trouble. You know, the equipment does know when to give trouble when I already like this close to crash now.
2%. Let me see how long that lasts. 4 + 8 + x 4 + 8 + x + 12 all over 4. What that supposed to be equal to, Nikolai?
>> Uh, it's supposed to be equal to 40. No, 10 10 10. My bad.
>> Right. Right. So the top the top would have to give you 40. So you have 4 + 8 is 12. 12 + 12 is 24. So we already have 24 in the bag. So to get the 40 you have to add 16. So 43 is definitely D.
All right. Um 44. They're saying a respondent from ethnic group P is selected at random. So selecting people from P. So that's over 60. How much people have a negative attitude towards mass?
24. That's going to be 24 by 60. And I'm not trusting myself. I'm put into my calculator and see the answer. Yeah, that's 2 over 5. So 44 is definitely C.
Um 45. Now 45. This was easy. Um B because that's a onetoone relationship.
45 was B. Um 46.
That's definitely D because it has a gradient of four. So M is four and the Y intercept is five. So 46D for sure. The maximum point is just how high it goes and that is 24.
That is 24. So that was definitely 47 A. 47 A. All right. 48 I plugging in minus 3 into that - 3 2 is 9. 9 by 2 is 18. 18 - 1 is 17. So 48 C 49 um if you extend it it's going to cut the Yaxis at zero. So 0 0 that was definitely a 49 a um 15 now right perpendicular if if a line is perpendicular then the gradient is going to be the negative reciprocal. So you're looking at rise over run rise two run across four. So 2 over 4 is a half. The gradient of the perpendicular line is going to be the reciprocal, which is 1 /2. Change the sign.
Wait, I hope I didn't just say 1 /2. If I reciprocate 1 /2, right? If I were to reciprocate this, that's going to flip and it's going to turn into two over one. I change the sign. That's going to turn to -2. Hopefully you understand. So the only answer with -2 in it is D. So 50 D.
50 was D.
Uh, last 10. Last 10.
51. That was that was a I know that is a for sure >> cuz you're just adding three to x to get y.
>> And the trick is in the brackets instead of the doain and the range.
>> Is it the do the same question?
>> Yeah. So, this is the domain and this is the range.
>> Okay. Is this correct?
>> Yeah. This is this is the doain.
Nikolai, you have real potential now. I could see you further on your studies than >> Yeah.
>> I don't know if you >> just right now. It's just right now. I stressing out because I guess seven.
>> That's okay. That's okay. You did real good. That's really good. Really good.
Um the answer for this was B because it say John starts from rest and accelerates uniformly. So starts from 0 0 and it's a positive gradient. So it's definitely the I sure about that 52b >> uh 53 complimentary that would just be sin 90 minus a it's without a doubt a 53 a s >> you put that right >> no >> no or that was wrong >> 54 was definitely D Because some of Okay, exterior angles will add up to 360.
Interior angles 360 as well quadrilateral cuz a quadrilateral is like this.
>> Yes, sir.
>> Um 50 55 it look is a reflection first of all is a reflection about the y- axis. Then it it looks like a it looks like um an enlargement with scale factor half about the original.
>> Yes sir.
>> Yeah that is 55B for sure. I'm sure about that 55B.
56 the answer is C.
56 the answer is C. Right? Cuz you're just making it two times smaller. Making the length two times smaller.
Um 57. I know that is 21 for sure.
Moving across two to the right and then one up. 57 is a um 58. Yeah, that's definitely a 58 is a um 59 definitely 90. 59 B.
60. Let me run through this question one more time.
Yep, that's correct. That's correct. So, the answer is 60B.
60B.
Let me explain it one more time.
Actually, let's do it. S explain it back one more time for them. One more time.
>> Okay. Now, um it says that the diagram shows a circle with center O and uh so you could zoom out a bit, please.
Sir you could zoom out a bit please.
Yeah. Thank you. And the points A, B, and C on its circumference. The line ECF is a tangent to the circle C and angle ACB and FCB are 34 and 74 respectively.
So they want us to find the values of P and Q. Now first instance when you look at this you can see the center is P, right? And then you will see on top is 34. The angle at the center is twice the angle at the circumference. 34 is standing on the circumference. So now all you have to do is times 34 by 2 because it says the angle at the center is twice. So 34x2 that's 68. That's one down. Next, if you look carefully, they say ECF is a tangent and it touches the circle and the circle has a triangle in it with a point C. So that's a tangent and a triangle. The angle formed between a tangent and the side of a triangle is equal to the interior angle. And it isn't just that little small part. No, it's that whole angle of the triangle.
So now we have to find for this little part here in order to find for Q. So we know that P is 68 and we know that A O B is a triangle, an isosesles triangle. So we have to do is we have to do 180 minus 68. We will get 112. And since we're looking for two sides, we divide that by two and we get six. We will get 56. So a and b are 56 respectively. We already have 56 and we have 74. So all you have to do right now is minus 56 from 74 and you will get that little cue right there. 74 from 56 that's 18. Your answer is B.
>> Right?
>> Yeah boy.
>> Sir I didn't mess up. These are my answers. I >> s I did mess up this one at first.
>> I stand by these >> and then I check it back and I get through.
>> So you get through.
>> Yes, sir. I get through.
>> I hope. Okay.
>> At first at first I miscalculated it and I was like what?
>> No, that's real. That was me first because I was like this not making sense. But then when I went back to it, I was like okay let let's actually lock in.
>> All right.
Nice. Awesome sauce. I stand by these answers. These answers have got to be correct.
>> Yes, sir. We get through just not by that much. No, no, no. Nikolai, you stay quiet, boy. You get >> I don't think you >> Yeah. Like, I don't think we should be talking. You should just be quiet in this instance. Just be quiet. Okay.
>> S where you guys get lower than Nikolai, that's for sure.
47 >> like 50 >> 47.
>> Okay.
You still you still do all right, >> sir? But that's not what I was aiming for. I was aiming for like in the 50s.
When I walked into that exam, I was like, "Okay, I get a few wrong. I know for sure, but at least it's in the 50s."
You could imagine my horror when we're on 50 something and I counting up the tally and I see I only on 45. I was like, "Oh my gosh, I didn't even reach."
>> So, you get like 24 marks. You get like 24 marks contributed to your percentage.
Like you have 24% here.
>> Yeah, >> that's not much give me.
>> Well, it's out of 30. So, you did you did you did decent 24?
>> Wait, what? Wait, wait. Repeat that.
>> Your paper one is worth 30% of your final grade. You know that, right?
>> And paper two again.
>> Paper two is 50%. 50.
>> What have I gotten?
>> Nikolai, you could do math for yourself.
Find 57 over 60 by 30.
>> No, 57 out of 60, you get 54.
>> Oh, >> no. 53. Actually, that is 88%. I got >> 53 over 60 out of 30, you get um 26.5 27, bro. And You can take that.
>> So like they just say you get say you get 28, right?
>> 28.
>> Yeah. Like what what we looking at?
>> Sorry. Sorry. Sorry. My brain just not working right now. But like Okay. I have 26.5 which is around 27, right? Um so I have 27. What you getting SBA?
>> I got 29.
>> What word? You pass already.
>> More or less. But that's like a like a a two a three >> like enough to pass.
>> Yeah.
>> Yeah.
Right.
>> So if I have a 24 to 30 and my SBA is a 20 out of 20.
>> So like you get 20 out of 20 in the SBA.
>> Yeah.
>> And you get like you get like 23 24. You have like 44 in bag. Actually you can scrape all six marks to pass.
>> But like >> but like we want we want like a one hour two. We want like a one hour or two though.
>> So So he So is he max for that?
>> I don't know. But like once you get like more than 60 I feel like two on more than 60 like 60 probably. Don't quote me. Don't quote me. I feel >> seven was on 7%. You see that Apple Pencil was on 7%.
>> Yeah. But um I really wish I really wish I could have teach you guys a bit earlier though and like like from form four or something. I really wish I could have teach you guys early.
>> Yes.
>> Well, boy, >> cuz you'll have some you'll have some good talents, but like there's only so much you can learn in five already, right?
>> You have me next year.
>> Okay.
>> Next year.
Right now, I don't want to hear you, Cassie. I don't want to hear you right now. I love you. But right now, no.
>> So, so you have me, you have me, you have me. I coming back again. Whether I'll pass or not, I coming back.
>> Real >> to have me for math, for physics, for maths.
>> That's what >> sir. I really need to for chemistry. So you see that paper one with that mix up and all kind when I do chem.
>> So since you're not having physics tomorrow, you decide like if you're not having physics or not or you're still like having physics tomorrow. Okay, maybe I could do Chem tomorrow in the evening and then >> wait advertise guys. Cassidy, Lucian, Miss Cassidy over here, she'll be doing a a chem b session. She's doing chem paper one, right? So I make sure and come tomorrow.
>> All the best I come. All the best I turn up.
>> I make I will be meeting too. I will be in the meeting too. I want to see how teach vibes. Um, Nikolai, you have any papers that like you want to do?
>> Uh, majority I did already. I could just >> 2015.
>> 2015.
>> Uhhuh. Yeah.
>> Nah. Do like >> on No from 2015. Boy, >> do like 2018. Somewhere around there.
>> Okay. All right.
I find we should do real pass papers like we just go through it and then it over like memory. You see like so we like a test to see like when we remember.
>> Yeah.
>> But then again CX playing up CX playing up real weird and I want to see I want to see what going to happen for bio.
Um and then we will see what might happen for >> CX just playing everybody buttons and getting >> railway.
>> You mean to tell me? Oh, you're not bringing it circle thems knowing that I couldn't get marks on factorization and especially my thing circle theorem. I was so vexed. Oh my gosh.
>> The first thing everybody come out and say, "Look, circle teran in paper one."
>> Yo, the sir, >> hey sir, I need you to do I need Cxc to to take to take heed that their paper did get leaked and just grade the paper on SB. That's what I need them to do.
Like just take heed your paper did get leaked 15 minutes before the exam. So that means >> next people say controversial stuff on my channel. Next time people say controversial stuff on my channel paper in 15 minutes I do figure it out.
>> I could do that paper. That's so true.
That's so true. Nol whoever whoever whichever one of y'all get that paper 15 minutes before God.
You're so lucky. You so lucky. So lucky.
Imagine my shock to come out to the paper two exam just to hear the paper get leaked 15 minutes before and I was like so y'all couldn't show me the paper >> that was my concern actually that was my concern >> seems so weird to know because to tell me no calculator for maths but in ad maths physics and chemistry you could use your calculator >> I barely need my calculator for chem paper one why am I allowed to use it >> yeah only there's only moles in here for really >> makes sense. Really makes sense. Like people are getting 60 for sure. Every single time.
>> Yeah.
>> But here what guys finish fast or two.
>> Yeah, >> for sure. So here what I'm tired. I going to go take a rest, >> right? I will neaten up the answers and send it to you guys. But um take care everybody. I will see you guys tomorrow.
>> One question before you go.
I will I will tell her wishes.
>> How we joining? How we joining the Zoom for chemistry? Is she making a Zoom link or >> I will tell you my Zoom. I will send you my Zoom.
>> Okay.
>> Um tell me the time and I'll send in the Zoom. I'll be there for a bit then I will head out.
>> Okay.
>> Make sure the vibes.
>> Yeah. Yeah. Yeah.
>> Of course.
>> So you can answer some questions too.
Yeah, >> interactive.
Cassie, just leave me alone, okay?
Because I don't know chemistry. Just leave me alone.
>> I go actually be active, man. I will I usually
