    ****ed it. Went to blow my nose for 2 minutes cuz of hayfever but ended up running out of time for the latter half of q8 - which means 10 marks down the drain. Also didn't finish the trig question so 1 mark lost. Overall looking at 64-65/75.

    My offer requires an A* in Maths but with only 63-64/65 in C4 and 65-66/75 in C3 doesn't look likely.

    You mean question 7? It wasn't a cylinder because it was curved at the end
    It was a cylinder. Area S was equal to the cylinder volume - the area under the curve.

    The mark scheme typically allows answers in hr:min form to the nearest minute.

    Yes, but i use volume of cylinder for height =17/2 + 1/2 = 9 Vc= pi(8)^2x9 = 576 pi and then i integrated between 17/2 and 1/2 and then subtracted the values. Is this wrong?
    (Original post by riffy123)
    I did that too and it must be right!
    No it isn't right. You're not supposed to add 1/2 to the 17/2. The 17/2 is the height
