    I choked, I cant believe I choked in this exam, the substitution should have been fine but... I forgot the basics, thankfully I miraculously guessed K correctly and followed on as normal ( I can't even remember how) so if I get a very lazy examiner I may even be able to trick them into giving me full marks (given just how much work I showed to get to that point) but that is unlikely. I thought that the paper was horrific when I first looked at it and freaked out, but in hind-sight, whilst it was pretty bad it was about the same difficulty as Solomon's (if not a-bit harder), I'm just banking now on low grade boundaries and good results for my other exams.

    I think you just answered your own question, unless you meant 30/75

    There was a formula at the bottom of the page. Ended up being 27pi/ln3 I think
    Please tell me radius had to be worked out by working the hypotenuse and halving it and then squaring it to get r^2 (r^2 was something like 85/root2? or no)

    Well, I suppose, but in the case of the question it would've been radians.
    Guys it's okay I appreciate you both. Just as long as the final answer WAS 0.4...?

    I have a few questions:



    1) how many marks do I lose if I found K as 2 and continued so I got the area as half? Out of the total 8 marks of the question.



    2) For the differential equation I found c correctly but at the end I couldn't get the final answer they wanted even doe part A was right. How many marks would I lose out of the 7?



    3) for the years question how many marks do I lose if I did the question in degrees?



    4) for the vector question how many marks do I get (if any) if I found the position vector of B for the shortest distance?



    5) for the cone question, do you get one mark for writing V=pi integral of y2? Also due to a lack of time I went to write what I would do instead of doing it, but I wrote the radius will be 9 for the cone et and you do integral until 2 minus the volume of cone from Q to P?

    Guys :
    100ums in C1, C2,
    97 in S1
    approx 85 in c3
    40 in c4

    Is an A possible
    Average of 84.4 UMS per paper, which would be an A. So yes, it is indeed very possible.

    Well that seems convoluted. It may have gotten the right answer, but you could have just used 9? Via the y coordinate of P

    The radius was the y coordinate of P. So no, you're method is incorrect. I'm sorry.

    They gave you the formula for the volume of a cone.

    too late now ... all recognition can be done by substitution
    make sure you can substitute
    How accurately can you predict what grade you'll get in maths?
    After looking at the papers that everyone and arsey have uploaded, I've been able to give myself a certain ums, but I'm not sure if it's completely accurate (I know how the mark scheme works so I gave myself a method mark where I thought I would get one)..

    Guys is 480 UMS for an A* for an A? I checked the June 14 grade boundaries and it says 480 under the A bit?
    The total UMS needed for an A* is the same as an A... it's just that you have to get at least 180UMS on C3 + C4 combined for the A*. Potentially, someone with an A could end up with more UMS overall than someone with an A* in Maths... it's just how it works.

    I think I got 100% in every paper but this one. I am so angry, I forgot to take 1 from the final answer.
