    Lets just hope grade boundaries are low. A* for 2011 was 58 and I found that easier.

    For the one about modulus, I only got 1 answer as x = 1.5a because when you draw the graphs they only intersect once - did anyone else get that?
    I think I only got one as well - is that wrong?

    Some people found it hard and some found it alright. A slightly harder than average paper.

    Relieved exams are finished. Good luck to people doing C4

    Community mark scheme (https://docs.google.com/document/d/1...it?usp=sharing) checked and corrected.

    https://docs.google.com/document/d/1...it?usp=sharing

    The corrections I've made are:

    2(i) deleted erroneous alternative answer, added modulus signs to lnx.
    8(i) marks adjusted down to 2
    8(ii) corrected inverse of g(x)
    8(iii) marks adjusted up to 5

    Lots of trig, no volumes of revolution or Simpson's rule. A tough paper if you don't like trig, and as a lot of students don't I'd say this was a slightly harder than average paper.

    For the iterative question did you have to put the answe to 4 decimal places or 3? I did everything to 4???? How many marks have I lost? I also therefore put the intersection point to 4dp?
    I've never seen a paper penalise putting it to too many decimal places, only too few.

    i did this aswell , would we lose a mark as i assumed in modulus it cant be a negative number aswell, so would we probably get 4 marks or 5 out of 5?

    I think i also put it to 4dp or 4sf, which ever one they asked initially , do you think they will deduct a mark and also for the integer one(question 3), if you wrote the answer as 31.8 or whatever it was would you lose a mark for not saying 31?

    and also what would 62.63 get do you reckon.

    For 8(iii) how many marks would you get for only getting one value of a?

    From the unofficial mark scheme I think I got anywhere between 69-59 marks (Being as harsh as possible and taking all answers I've forgotten as 0 marks for the lower bound) What range of Ums scores do you think I've gotten?
