Math S1 Students, Time to perform 🚀

Added: 2026-05-11

[00:00:00]As-salamu alaykum everyone. Hope you guys are doing well. So, I'm making this video to wish you guys the best of luck.

[00:00:06]Students S1 students who have their exam tomorrow. So, just a couple of things that I wanted to talk about. Now, first of all, remember that in S1, time is very limited and you literally do not have a single minute to waste. So, as soon as you get the paper, as soon as you start, make sure that you are 100% locked in for the next 75 minutes. Yes, I want you to think of time as minutes, not in terms of hours and minutes. So, you have 75 minutes to complete six or seven questions, depends on the paper that you get. And do expect one or two difficult questions, but don't let those one or two difficult questions ruin the entire paper. So, start with the easier questions. Start with questions of topics such as graphical representation of data, measures of central tendency / spread, you know, questions which involve mean, median, and variance, standard deviation, all that kind of stuff. They're lengthy, yes, but they're easy. The normal distribution, majority of the questions of normal distribution are very, very straightforward. Yes, lengthy. Yes, time-consuming, but they're easy. There's not much that's happening in it conceptually, very straightforward. So, you will get your confidence level high when you start off with the easier questions. Then there's obviously binomial distribution, also easy. Sometimes geometric distribution questions are complicated, but majority of the questions are easy and I hope that in tomorrow's paper also you come across any questions. So, remember if there is a question of binomial which is then followed by normal approximation, you have to apply continuity correction.

[00:01:27]Do not forget to do that. Remember all the rules of continuity correction.

[00:01:30]Remember all the rules of geometric distribution. Watch out for keywords like at least, at most, no more, greater than, lesser than, within. So, these are all the keywords that you must pay attention to when solving questions of normal distribution, binomial distribution, or geometric distribution.

[00:01:46]Then after that, if let's suppose there is a question on permutation and combination, remember watch out for what the the says. Does the question say uh not all are together, no two are together. So, watch out for that. Watch out for all the methods that all the possible ways that you can fulfill whatever the given condition is. If there's a question which involves, let's suppose, variance or standard deviation, remember to find out the standard deviation, you have to take the square root of the variance. Don't forget to do that. If, let's suppose, there's a question of histogram, make sure that you've made the data continuous. Make sure that you've made the data continuous before you calculate the mean. Okay. So, all these little little things, make sure you will you will not forget if you're 100% locked in. And if you if you make sure you review your notes before you go to the exam. Do not solve the past paper. Make sure that you don't put yourself in a testing position. I'm sure at this point there are a lot of alleged leaks circulating. So, please make sure that whatever you think is a leak, whether it's whether it's legit or not, there's no way to find out before the actual exam. But, whatever it is that you come across, make sure that you report it to Cambridge. Don't wait that, "Okay, let's wait till the exam and see if this is the actual paper or not, and then I'm going to report." Don't do that. That's a horrible strategy.

[00:02:59]They're not going to believe you after that. They just want an excuse to, you know, to to sort of sweep this under the carpet anyway. So, if you don't report on time, they they will have the perfect excuse to do that. So, yeah. And uh there are a lot of things that you can use your calculator to check your answer. We've discussed majority of those in the live streams. Uh so, that is measures of central tendency / spread, you know, mean, variance, standard deviation, all that kind of stuff. And also discrete random variable.

[00:03:25]In discrete random variable, when you when you're supposed to calculate the mean, which is the expected value of X, and variance, you can use your calculator to check your answer.

[00:03:32]If you don't remember the formula, please remember that there is a formula sheet that's provided to you, so you can refer to that.

[00:03:38]And just make sure that you're using the correct formula. Don't doom solve. Don't ego solve. Don't think that you don't need to use your calculator. You don't need to show your working. You have to show your working, especially for binomial distribution if you're working out multiple cases.

[00:03:49]For geometric distribution, also, you have to write down all the cases that you've considered. Don't just write the final answer. Make sure that you write down all the cases that you've considered. Same goes for normal distribution. Make sure you write down the value of X, the Z value, the phi the the value that you get after you read the table, and then in the end, your final answer, whatever that is. Okay?

[00:04:09]So, So, I was I was I was telling you all the stuff that you can use your cal- calculator to check your answers. So, you can use your calculator to check answers of measures of central tendency {slash} spread, mean, median, mode, variance, standard deviation, discrete random variable, binomial. We just learned how to do that uh in the last in the binomial stream, and then there's normal distribution.

[00:04:27]So, all this stuff, you can use your calculator to check your answers. So, just make sure you do that.

[00:04:31]And uh again, do not forget to apply continuity correction if there's a question of normal approximation. Reason why I'm saying that is because I've read it time and again in the examiner report that this is a very common error. It's not that students don't know.

[00:04:42]Okay, when they're practicing, obviously, they learn this concept and they apply it, but it's just that they forget. So, make sure that doesn't happen to you.

[00:04:49]And I guess that is it. Just make sure you have a properly functioning calculator, and also a backup calculator. Make sure that you have all your stationery in order.

[00:04:58]And uh when you're drawing graphs, whether it's histogram, cumulative frequency, make sure that you first If the graph is already given, make sure that before you take you take any readings from the graph, you get yourself familiar with the scale. And before you draw the graph, make sure that you pick a nice suitable scale, which you're going to use to draw the graph.

[00:05:16]And uh I guess that is it when it comes to probability, make sure that you have If a question is on conditional probability, make sure that you've identified what the condition is, and what are the scenarios that you have to consider. Okay, remember whatever comes after the word given, the probability of that comes in the denominator, and whatever two events that the question is talking about, we look at the probability of both of those events occurring together. Okay? So, just review your notes before you go to the exam, and uh I'll be waiting to hear from you guys how your exam goes. So, I wish you guys I wish you all of you the best of luck.

[00:05:50]And inshallah you guys will do great.

[00:05:52]So, I'll see you I'll speak to you guys inshallah after the exam. So, take care.

[00:05:55]Good luck once again. Remember me and everyone who has been a part of this journey with you, whether it's your teachers, your classmates, your parents, everyone around you, whoever has been a has played a role to be a part of has played a role in getting you this far, remember all of them in this journey in in this in your prayers. And pray for yourself also obviously. So, yeah I'll speak to you guys after the exam. So, take care everyone. Allah Hafiz.
