    Think I got 73-4 in C3 but C4 didn't go too well- hoping to scrape an A* overall.

    No worries, I'm hoping my 68, 70 will get me an A*
    hope it goes well for you!

    70/75 in C3, 69/75 in C4, enough for an average of 90 UMS?
    probably... 70 in C3 defo an A*, 69 in C4 may not be an A* this year but altogether it should give you 90+ on average

    Would 71/75 in C3 and 66/75 in C4 be an A*????
    71 in C3 is certainly an A*, 66 in C4 is most likely an A, but your C3 should pull up the average and probably you'll have the A*

    what if I got 75/75 in C4 and 61/75 in C3, A*?

    coz for last yr, 59 was an A and the difficulty and length is comparable to this year's, also for 2014 it was 60 for an A but obviously look at the paper it was easier...so maybe i will jsut scrap an A*?
    I think the C3 A* boundary will be around 65-66 so you'll have the A*

    probably won't be an A*, the boundary for an A will be on C3 will be higher than 61, there wasn't anything on there that hadn't been asked before

    probably thought 4 - 4sin^2theta was the same as costheta

    I see where I went wrong now, thanks haha, how many marks is that then for question 6 do you think, including the method marks I will hopefully receive for that question, as I think I made the correct method for getting to sin^2 and then integrating it?

    Made only one mistake. For the volume questions, I took the length of the cylinder as 8 instead of 8.5. This gave me the wrong answer of 512pi - 'whatever it was' rather than 544pi - 'whatever it was'. One mark lost for answer.

    Would I lose 1 or 2 marks for method? 72 or 73 for me. I'd really love it if someone could reply and say what they think?

    yea but even 2014 easier papers have 60 ums for A and last year's with similar difficulty had 59 for A so how can it be higher than 61? ppl suddenly get much smarter this yr?

    fp2 doesn't contribute to maths A level.

    Unless you're taking an A Level in Pure Maths

    For the area of the triangle in the vector question I used sin of a rounded angle from cosx=4/5, meaning I was just off 2.4, do you think I'll still get full marks

    The volume question started by asking to integrate (2x+1)^3/2 or something?

    Gave a graph of (2x+1)^3/4 and we had to integrate that squared (using the above) times pi and subtract it from the volume of the cylinder which was trapped between the x axis and the line y=8 before being rotated.
