GCSE Maths Higher Predicted Paper 1 | 14th May 2026 | Quick Walkthrough

追加: 2026-05-15

[00:00:00]The GCSE maths paper one is in less than 5 days, so now is the perfect time to be watching this video. I'm not going to waste your time. Let's get right into it.

[00:00:10]Let's simply write out these mixed fractions as improper fractions and then add them.

[00:00:24]Then convert it back into a mixed number.

[00:00:30]Use our KFC method.

[00:00:39]Simplify to make it a little bit easier.

[00:00:47]We can multiply both of them by 100 and use bus stop.

[00:01:01]Then make it such that there's 3x in both and subtract.

[00:01:17]>> [music] >> And then solve for x.

[00:01:33]We can create an equation to represent this.

[00:01:37]We can say the total is equal to 4x + 2x + 6x, which is equal to 13x.

[00:01:45]Then the number of yellow counters, 6x, is equal to number of blue, 3x + 39.

[00:01:54]Then we can just solve.

[00:02:04]Let's just put everything in.

[00:02:15]And then we can write out the numbers that aren't covered here, [music] which are odd numbers less than 13.

[00:02:24]Which are 3, 9, 13, 21.

[00:02:28]2/5 of the pots are unused, so we can just calculate that.

[00:02:37]And then small to medium to large can just be written as 1 to 3 to 12.

[00:02:45]If we write one medium to four large with three mediums, then we'll get 3 to 12.

[00:02:52]So then unused small pots are 1 over 16 * 160, which is just 10.

[00:03:02]And then we should read the question carefully because they asked us for the percentage in terms of his total pots, which is 2.5%.

[00:03:20]So we're looking for CAB, which is at the top here.

[00:03:24]This angle AED is equal to 180 - 122, which is 58.

[00:03:31]That's because angles on a straight line add up to 180°.

[00:03:36]And then we can figure out ADE, which is also equal to 59, which is at the bottom right there, because corresponding angles are equal.

[00:03:46]So now CAB is equal to 180 - 58 - 59 because angles in a triangle add up to 180 degrees.

[00:04:04]Which is 63 degrees.

[00:04:06]>> [snorts] >> Let's find out the area of this area on the bottom here.

[00:04:11]First.

[00:04:12]We know that the volume is 24 and that volume is just [music] the area times the height. So, we can just do 24 divided by 4 to get 6 as the area.

[00:04:27]And then, pressure equals force over area as it says in the top right.

[00:04:31]So, force equals pressure times area.

[00:04:34]Then, we can just do 60 * [music] 6 or 360.

[00:04:44]To find the mean weight, we can just >> [music] >> find the total weight of boxes, subtract, and then divide.

[00:05:04]Now, this is a fractional index just like I've taught before.

[00:05:07]We'll cube root it and then take it to the fourth power.

[00:05:27]So, with this graph, we can find a few important details such as the median and such.

[00:05:51]>> Now we've got our box, so we can do our whiskers with 0 and 112.

[00:06:00]Excuse my box plot. I'm a little bit lazy to use a ruler.

[00:06:05]Okay, let's compare our distributions.

[00:06:08]So, the delays on Thursday were longer on average because the median was greater.

[00:06:14]And the spread of delays on Thursday is wider the interquartile range is larger.

[00:06:21]They say on Friday there were more delays between 24 and 48 than between 0 and 10.

[00:06:31]Is that true? No, that's not true because we know that in between each of these sections there's 25% of the values.

[00:06:40]Let's move everything to one side and solve.

[00:07:05]This length here [music] is 10 pi.

[00:07:08]And let's just call this theta. So, we know that theta over 360 times the circumference is equal to 10 pi.

[00:07:43]And so, we can solve for [music] theta like that.

[00:07:47]Now, let's find our area.

[00:08:17]Let's write our proportions out.

[00:08:50]Now we have them separately, we can combine them.

[00:09:12]Sub in our numbers like usual.

[00:09:39]Then, let's find the inverse g.

[00:09:42]I'll just write down g again down here.

[00:10:20]Um rearranging This rule requires some careful rearrangements.

[00:10:37]And some careful multiplication.

[00:11:02]If they're perpendicular, you know that's the negative reciprocal.

[00:11:25]We can draw a tree for this if you'd like.

[00:11:38]>> Since we already removed the red marble, there'll be one less red marble.

[00:11:42]And then the total will be reduced by one, too.

[00:12:05]If the surface area is 25 pi, that must be equal to 4 pi r squared.

[00:12:10]So, we can use that to get our radius.

[00:12:17]And then we can just put it back into our equation.

[00:12:37]Now, we just rationalize our denominator here by flipping around the sign on the denominator.

[00:13:20]Okay.

[00:13:21]So, let's >> [snorts] >> complete our square.

[00:13:28]I like to take out the minus first.

[00:13:34]But, you can do whatever you like.

[00:13:54]These kind of questions often take quite a while to crunch down the numbers.

[00:14:07]But, now it's finally time to put the negative sign back in.

[00:14:12]So, our turning point must be minus 2 13.

[00:14:18]Oh, no, vectors question.

[00:14:21]Let's write our ratios down on the diagram first.

[00:14:29]Oh, I hate these questions.

[00:14:50]So, now since we don't OC, we just know that OP is some multiple of that.

[00:14:59]We can also write OP in a different way.

[00:15:02]Perhaps, O to A plus some multiple of A to D.

[00:15:28]>> And so now we know that these two must be the same thing.

[00:16:15]And so can also get K.

[00:16:25]So now that we've got K as 2/5, we know that OP is 2/5 of OC.

[00:16:34]And so our ratio is OP to PC, which means that PC is 3/5 of OC.

[00:16:45]Which would mean that OP to PC is 2/5 to 3/5 or simply 2 to 3.

[00:16:58]And so I was hoping to not see a vectors question, but you can't improve on something you don't practice.

[00:17:05]>> [snorts] >> Now, I hope this video helps you, but the practice does not stop there.

[00:17:10]You need to go out and practice yourself. That's the best way to go through this.

[00:17:16]So, good luck, Radiance Squad.

[00:17:22]>> [snorts]
