    I forgot to simplify in 7(b), I left is as 9/6(x^2)+54
    Will I lost any marks for it?
    Question does not ask for it in its simplest form. You will not lose any marks, I did the same thing.

    Rep:
    Cheers Arsey! Messed Q1 up - silly addition but just been through, and I think I have 66/75 give or take I need a B for uni so hopefully C4 won't be too bad and I will get my B

    Well done/good luck/better luck next time everyone! (please circle appropriate answer :P)

    Rep:
    I thought it was quite hard- not enough time to check answers/write down what I got :P
    Feeling slightly more confident that I haven't completely failed after looking at the markschem- maybe around 60/75 if I didn't make any additional stupid mistakes..?

    Rep:
    Can't believe I think I managed to misread iteration question as x0 = 0 rather than x0 = 1

    Stupid loss of an easy 3 marks.

    Rep:
    I count 48/75 , really upset past papers was getting around 67 , can anyone guess what 48 would be ??? Please say a C haha

    Rep:
    For 6e) where you had to draw the exponential curves on the graph I didn't draw on the asymptotes because it didn't ask for them. Do you think I will lose marks for this?

    And on 7b) is Arsey saying there is two answers? because I left mine like (1/6)cos^2(arctan(x/3)). Is that ok as a final answer?

    Other than those things I'm a bit unsure about I reckon it all went pretty well A* here we come!

    Cheers Arsey. How many marks do you think I would lose for not solving 3a) properly? I did it right up to root(3)sin3x + 3cos3x = 0 but I couldn't figure out how to solve so I just stuck in random pi values until I got the right answer and wrote that down.

    Rep:
    How many marks would I get for..

    3a) only did the differentiation, couldn't find turning points
    3b) My gradient was wrong but x and y values were right
    7b) Only reached up to 1/6sec^2(2y)

    Would appreciate it if someone could tell me, thanks

    Rep:
    lost majority of the mark on 7b whyyyyyyyyyy

    Rep:
    stay awake till now just to see this haha

    Rep:
    For the differentiation questions i didnt put answers in their simplest form
    For both i and ii, how many marks will i lose for that?

    Rep:
    On question 6E would I lose marks for not adding in asymptotes/line of symmetry?
