    for the last question, 9a, i had the values of x = 30, 150, 390, 510 but then i divided it by 3 and took away 15, didnt get the same answer as u for the that part.
    for 9B, i had the same idea as u, so did the 1st two lines right but then i kinda messed it up afterwards, how many marks do u think i lost overall for that question?

    You had to add 15 first then divide by 3.

    Unfortunately very high. I would say A is above 62. I would say this Jan series more candidates are resisting to get an A as they probably are continuing maths for A2. Few exceptions like me just sitting in their AS year. I would say this paper and June 2011 were the same difficulty.

    If there was an option to retake this paper now, I would do it. I made so stupid mistakes.
    I really need to get in the habit of reading the questions properly. Hopefully i got 65+. In june 2011, i got 56 which was like a 71UMS

    C2 is a calculator paper. It has elements which require no calculator assistance - like rearranging a equation, differentiation, intergration.
