    I completely messed up this exam. I think I'm gonna get 60 UMS. Is it still possible to get an A overall having 86 average from last year? Also, I'm doing D2 as part of AS further maths, it can count towards my maths if I get a high mark in it, right?
    I'm in a very similar position to you, let's hope the grade boundaries are lenient this year. The paper with the lowest boundaries was June 2013 and i'm 100% that this paper was harder so I guess we should have some luck on that front

    On this question (2b i think), I factorised a -4 from the top after differentiation then cancelled out by an x^2+5 from top and bottom..... Was that okay of me doing that?
    No because the top simplified to 4(5-x^2)

    On the 2cot2x + tanx = cotx question in part b. My polynomial was y2 - 3y - 1 = 0. I did complete the square and I put
    (y + 3/2)2 - 13/4 = 0. Which is wrong, should be -3/2. I found solutions but they are wrong. How many marks will I lose out of the 6?

    My initial reaction when I came out was 66 for an A* but having heard others I changed my mind to 65, so I personally think you've got an A*

    Im unsure on my trig solutions for Q8b because I can't remember 2 of them but that should be max 1 or 2 marks as otherwise I got the same as the model answers for the rest. What does everyone think full UMS will be just so I can feel as best I can going into C4 lol *prays*
