    Do examiners allow marks for errors carried forward across parts of a question?
    it depends on the questions, sometimes the mark schemes allows error carrying forward and sometimes it doesnt...usually it does not...

    Would 65/75 C4 and 68/75 C3 be an A*. Trying to find worst case scenario ?????
    Thanks

    Likely to be ~90 UMS in C3 and just under in C4. It could be an A* but it'll be very, very close.

    OK these are my answers can anyone add to/correct them?

    1) didnt write it down
    2) A= 1.083
    exact = 8/3l(2)-1
    3) 3pi+62/pi+22
    4) x=60e^-5/2t
    t= 633 mins
    Q?? -2ln(y)+3ln(3y+2)
    6??) lambda=8
    area = -3root3 -4/3pi
    Volume of rev question k=17/2
    V= 1696/5 pi
    Parametric question m=-5root3 / 16
    x=4 y=5root3
    8) costheta=4/5
    length=2root2
    area= 2.4
    E= (-7,28/5,21/5) (-3,12/5,9/5)

    wont all be correct and cant remember which order they were in too well but its a start

    Last vector part is wrong

    A* is 480 UMS or more overall from 6 units, plus 180 or more UMS from C3 and C4 combined. This can be 90 and 90, 88 and 92, even 80 and 100. There is no requirement to get above 90 in both. If you're right about what you've got then you should be fine.
    I thought you needed 540/600 UMS for an A* in maths ?

    That is not true.

    You could get 200 out of 300 at AS, 100 in your second applied unit, 80 in C3 and 100 in C4 and that would give you an A*, for example.

    Would 70/75 in C3 and 67/75 C4 be a sure A* do you think?
    Think it'll be close. 70/75 will probably be ~93 UMS. Depends entirely on where the A* boundary for C4 lies.

    Well last year it was 65 for an A* in C3 and I doubt the boundaries would fluctuate any more than 3 marks and in which case you'd still get 90 ums, but for c4 you needed 67 last year so you're likely to get around 87/88 ums for getting 65 so lets say boundaries stay around the same as last year then you might scrape in...

    How many marks was 6C and 6D worth. Will I get error carried forward for accidentally taking out a factor of 2 and getting lambda = 16?

    I did the same, I can't see us losing more than two marks due to follow through
