    If I got 63 on this paper, and 70 on C3, would I have an A* overall
    To get an A* in Maths, you need to average C3 and C4 to be at least 90% (180/200 UMS), and at the same time get at least 80% overall. (480/600 UMS)So if you say you got 63 in C4, and 70 in C3, then by considering the standard grade boundaries (80% - A, 90% A* etc..):

    C4: 63/75 = 84/100 UMS
    C3: 70/75 = 93/100 UMS

    so the average UMS in C3 and C4 is 89%. So that wont get you the A* even if you get at least 80% overall, however, the grade boundaries vary, and this year im definitely sure they will be low, so Im sure you will get an A* in the end. This year has been very hard to most people.

    The answer was 13pi/ln3, I think you forgot to take away the volume of the cone.
    what was the volume of the cone!?

    Oh no, another one of these people. I'm not going to go through the effort of checking if another user is male or female, they is too confusing because English is a dumb language. Should I start using the Xe pronouns and conform to tumblrinas?
    The only thing I could think of when reading your post.

    This may be considered offensive for some tumblrinas.

    grade prediction?
    C1- 86 ums
    c2- 67 ums
    s1- 69/75 marks
    m1- 52/75 marks
    c3- 52/75 marks
    c4- 60/75 marks
    ?
    86 + 67 + 92 + 69 + 69 + 80 = 463/600 UMS, thats 77% overall, which is a B.

    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?

    That is not technically correct; as long as you carry the π/180, it is possible to use degrees.
    Well, I suppose, but in the case of the question it would've been radians.

    Do not say that; C3 boundaries will be lower, and even with C4 boundaries it is still a potential A*.
    to be fair thats worst case scenario, as you can't really tell how many method marks there are

    There was a formula at the bottom of the page. Ended up being 27pi/ln3 I think

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

    To get an A* in Maths, you need an average of 90% UMS across C3 and C4 + 480 UMS overall. If you got 480 UMS overall, and got an 89% average or lower across C3 and C4, that would be an A.

    In the case of the question you could have still carried the π/180. It is universal, irrespective of the case, that you can convert. Nevertheless, the answer in radians or converted degrees, is around 0.4.
