    Screwed up the finding A question equated it to the real part instead of the imaginary part (which was a quadratic) :/

    disappointed.
    I didnt realise that u had to apply completing the square to the matrix question.....lost 2 marks
    I couldnt prove that alpha was the root, i equated the equation to 0 and got the same but positive value (im not sure whether it is correct)??
    i couldnt find a and b nonetheless i managed to create an equation using the imaginary roots and did a bit of working that led nowhere. As a result i only showed the imaginary roots on the argand diagram....lost 4 marks
    For the last part in the matrix question i got k as x/5y, correct?
    last part i didnt manage to get it to k+1....lost 3 marks

    End result=resit

    Summation proof was alright imo. I think i got that correctly.
    What i couldn't find was (b) in raphson process and 7(d) about T which maps points onto itself for a value of k or something.

    **** me that was unexpected. so many questions i got stuck on, p and q for complex roots, descriptions of geometric transformations, proof of summation, coordinates of parabola

    i've been getting like 98% on past papers and on this **** i must have gotten something like 70%

    That was a very difficult paper compared to previous years. I completed both gold level papers yesterday with 1 or 2 small silly errors however today I think I got roughly 60/75. I am quite upset as I need to get 3 A's for UCL and I needed to do better on this paper.

    That was awful, on past papers I finished in plenty of time and always got full marks or only dropped a few. I barely finished and when I started checking I noticed a mistake that I didn't have time to correct

    OMG
    The last question 9b I cannot prove!! I equate them together but there was 5p cube sth...
    Probably gain one mark for the method.
    Also, for 9c, I forgot to equate the y coordinate to zero!! My mind was all about the x coordinate greater than zero lol.
    Waiting for Arsey's answer...
    Let's hope the grade boundary of this will be around 66/67 for 90...
