    I still have no idea how I didn't get 100 for C1, and C3 I somehow wasted enough time that I couldn't to the last part of the final question... worth like 4 raw marks 5 more mins and I would have got 100, even 3/4 marks in that question would have given me 100 UMS! (because that paper was 74/75 for full UMS)

    I'm ungrateful (:lol:) tbh, I should have done better.
    C1 fair enough, me too.
    C3 your own fault :mmm:

    I know I'll probably get hate for this, but 95 in C3 seems quite subpar... and not representative of my ability imo

    97/98 would have been fine, but 95 :/

    Here is my plan:

    Smash C3 and aim for 100.
    Try and get a good A in C4.

    Which definitely means an A* if I get C3 100 and any A in C4.

    Then, say I applied for Cambridge. I would do my three strongest FM modules, to show I can get consistent 95+.

    Good plan?:ahee:

    Why not smash C4 as well? :sly:

    That is true, I just can't see why you wouldn't like them as they're fun in my opinion

    Chemistry I want to prioritise in a way... Although knowing me, I'll put C4 first.

    It's hard though

    \dfrac{2\tan(x)}{1-\tan^2(x)}
    Not sure about an easy way :laugh:

    Just use the formula in the booklet where both A and B are x

    I just derive it from the addition formula in the formulae booklet :holmes:

    I just remember the formula for tan(A+B) then work it out, after a couple of times you just remember these things

    You will if you do S1 - thank god for binomial tables :ahee:

    Inverse trig?

    So if I asked:
    For a random variable X \approx B(20,0.5)
    Find:
    P(X \leq 18)
    You'd do  P(X=0) + P(X=1) + . . . + P(X=18)? :eek:

    EDIT: Can't seem to get the tilda so I used approx

    Hi can someone help me with S2 hypothesis testing please.






    I done the part to the get the first 3 marks but im not seeing where to get the 2 and the 10.

    I would assume P(X<=A) < 0.025 but I dont know to go from there.

    Like for two marks if they ask:

    Differentiate sin^-1(7x) I do it from scratch

    Yeah :/ it's never that high though, most I've done is... About 6 of them

    Here's a nice logs question.
    Show that the solution for x in the equation.
    6^x = 5 \times 9^x
    Can be written as x=\dfrac{\log_3(5)}{\log_3(2)-1}
    Okays thank youu I'll try it then post it
