    What did everyone get for question 9) I got y = 32(1 + ln(x))^2
    There was NO question 9, think you did the wrong paper.

    For the decay question did anyone get t = 640

    so 640 x 24 x 60 = answer in minutes?

    For the last area did anybody also get 6 units^2 ?

    Found the paper ok, some tricky questions but only thing i think i may have got wrong fully was the very last question.

    I found the distance of the direction vector and said linda = 1

    then i used the vector equation P +/- linda(direction vector) to get the two co-ordinates of B. I didn't have enough time to finish it but i knew the methodology so hope i got a few marks for it. one of the B co-ordinates i got was -4i +9j +5k
    I did the same thing as you on the decay question because did integral(-5/2x)dx = integral(1)dt instead of integral(1/x)dx = integral(-2/5)dt
    Very annoying because that question was 7 marks

    yyeah i almost missed it, it helped for the volume of revolution question tho

    thinking you may get marks for it if you did it correctly in the volume question, iv seen that before where in a MS if you miss part A and it helped for part B but you did it correctly in part B you'd still get full marks

    What would 73 on C3 and 72 on C4 be overall be in ums? I need to get an A star in maths for my offer. I might have lost a few more on each but thats my estimate.

    Would there not be marks carried forward? the second question required a correct answer from the first :/

    Is UMS cap usually 75/75? Does it ever get lower?

    For 6c I got Lambda = 16, as if dx = 8sin(theta)cos(theta) d(theta), when you rooted the 4 after taking it out the fraction, you have 8 times 2 and therefore 16?? Or am I just being dumb?

    Both likely to be an A*. 71 in C3 and 72 in C4 would have been 195 UMS last year.

    Was it 7 marks just for solving that differential or the whole question?

    From an optimistic point of view yes! But I think it is very unlikely :/
