    Edexcel AS Maths Discussion Thread - 2018 Edition


    Hey guys, I thought I'd make this niiiiiice and early so we can all share how we're preparing for our Maths exams this year?

    Statistics 2
    Date: Monday 25th June 2018
    Time: Morning
    Duration: 1 hour 30 minutes
    Days to go?: 1 :crazy:

    Probably the most important way to prepare for maths is to do plenty of past papers! You can find all Edexcel Maths past papers here.

    Also, Physics & Maths Tutor has some good resources for revision - everything from revision notes to questions on specific topics. Materials for S2 can be found here.

    Good luck with the preparations everyone, let the countdown commence!

    S2 is a nice module, however the wording can be really hard to wrap your head around sometimes, but once you do it's pretty straight forward

    For Binomial and poisson questions, do we need to show working if the question can be done on a graphical calculator.

    Example:
    Number of misprints per page has Poisson, mean of 2.5,
    Find probability of no misprints(2 marks),

    If I just write X~Po(2.5)
    P(X=0)=0.0821

    Will I still get full marks even though in the mark scheme, you get an M1 for doing P(X<=1)-P(X<=0)?

    Could they ask you to prove the formula VAR (X)=(b-a)^2/12 for Continuous Uniform Distribution? It's just that there's an example on it in the textbook.

    I keep running out of time but I hear people finish this paper in like an hour and it's meant to be easier then S1. Are there any well known or not so well known shortcuts I may be missing out on (that some of you might want to share)?


    I am only saying this because, I would try to get S2 perfectly but I now have C4 to prepare for and then after that it's FP3 and S2 clash on Monday. (Yes, I regret taking Further Maths but I can't quit now).

    yes, I think I have seen it in a past paper, can't remember which one.

    I just checked the book, and it says that we may be needed to derive the Variance Var(x) and the mean E(x) formulas from the first principles. It is derived on pages 71 and 72.

    If I find more formulas that we may need to prove I will update this post.

    Guys, S1, M1, D1 & M2 have all gone pretty bad so far (from what I have heard). Do you reckon S2 will be bad too?
