    Anyone know if the UMS needed for an A* needs to be 90% in C3 and separately 90% in C4 or can it be a combined total of the two?
    Combined total of the two. What does everyone reckon full UMS would be for this paper? Lots of silly mistakes

    y = e / (2(1-x)^1/2(1-ln(2(1-x)^1/2))) ?
    yep, I got it in a scummy way, hopefully the examiner sees my final answer and just presumes that i'm a genius and found it in my head, even though I essentially guessed what it was with some bs working

    k was 2 right? For the d theta/dx question?
    I got k=2! But some people I know got k=6 :/

    It's the combined total! :-)

    Did you get a and b in part before as like 5/2, and 9/2 (one of them was minus but can't remember which)?

    I got this too
    is that the same as y=e/(x-1)^0.5(1-ln(4-4x))

    Usually they just ignore extra ones not in the range, but I'm wondering if they were being sneaky here.

    Uuurgh so annoyed core 3 went really well for me but this didn't. Hope my core 3 ums brings me up to A* :/ For the integration question I got 9/2ln3 -69/2, but this comes up as a negative number.. Have I done it wrong?
    It didn't ask for area, so you're fine

    It wanted it in the form of e/ ( f(x) ln (f(x)) or similar, so the f(x) had to be the same.

    I got that too because I stupidly took the 12e^-2 to the top instead of leaving the 12 on the bottom -.-
    yeah that's what I did, I assumed 1/e^-2 = e^2 lol how many marks do you think we lost for that?

    Probably two - a method mark and an accuracy mark🙄

    it's the average of the two, for instance 85 in c3 and 95 in c4 would still get you an A*
