    I thought I could do all questions but I didn't!! Exams are simply not for me...

    For my minimum grade predictions I need now A in C4 for overall B, or for my maximum marks I got, I will need overall B in C4 for overall B.

    My days, pissed me off. How did you FLIPPIN do the question after you proved cotx? I just could not simplify it!
    use the cot^2 +1 = cosec^2 identity

    Not too sure its one of the 2, because I remember seeing 32 and 3, so I think 1 of us just read the signs wrong, worst case one of us will lose 2 marks
    I got 29/2 at first when I incorrectly used 0.5 as gradient. Using -0.5 gave me 35/2

    You were probably putting the numbers in the wrong equation, you had to put them in g(x) = 2x +7 (can't remember what it was), not g(x). I was getting so angry at that question then I realised XD

    trust I put it into every equation available on that page but still didn't get that 1 mark. (1 mark for the interval??)

    anyone get x = -21.5 for prove alpha is a positive root thing? 2 marks

    Also had no idea where to put the 1.36745 and 1.36755 or w.e the numbers were to prove 1.3675 was a root etc

    Overall I think semi hard paper, harder than most of the papers I've done I think A will be in the high 50s / low 60s

    A* like 63/75?

    The turning point had to be between pi/4 and pi/2 so the answer was 0.9 something
    Wasn't the range -pi/4 to pi/2?
    That's what I remember it as actually so maybe me and thehollowcrown are right
    We were working out the x value and the x value had to be between pi/4 and pi/2 :/

    Yeah In an earlier part of the question is said g(X) = 43 plus 2x or something which gave g(X) -43minus like 2x (I just remember one number was -68) then j got a change of sign was this right ?! Sorry haven't explained very well

    Anyone else struggling to get their exams finished in time?

    Throughout GCSE its never been a problem, nor was it last year in AS, but throughout my A Level Physics and Maths exams this year, its been very difficult to get them finished on time. I had to leave 9c in this paper as i simply ran out of time

    Other than that, the questions were okay, i feel confident i have done them correctly. Maybe its worth sacrificing a couple of marks for to make sure i dont **** up any of the other questions by rushing and making silly mistakes!

    that exam was easy. For the cotx question, I changed the equation in terms of tan2x=2/3. Then worked out the four values of x.
    I did this too, idk why people did quadratic formula
