    how many marks was the spheres question?
    5 I think. If you messed up the bounds you will probably get error carried forward marks since the mark scheme for this question will probably be split in bands but Edexcel aren't very kind in that sense.

    63 degrees - 48+15
    I think so. Was the theorems used the fact that two radiuses create an isosceles, angle at the center is twice the circumference and the opposite angles in a cyclic quadralateral ?

    I got upper and lower bands right and converted cm to mm but I forgot to cube it. How many marks off do you think that would be?

    I thought it was OK.
    Hopefully grade boundaries will be lower this year as it was tougher than the January paper half way through the paper.

    There is an unofficial mark scheme in progress.

    for the sphere question, all my working was completely correct but I forgot to convert the radius of the sphere from millimetres... how many marks will that cost me?

    I remember it being tan inverse of 8/ root 314 giving answer of 24 or something like that :/
    I got that as well

    If for the sphere question, I didn't put anything about bounds, but I calculated the volume and divided it by the number of spheres, i.e I did 91.125/0.036pi, how many marks would I get?

    I got 2/7 for the probability question; if I forgot the combinations of 2,2,2 how many marks will I get?

    One or two max I'm afraid, these are the likely mark allocations

    M1 for correct calculation of 'one' combination of 1+2+3
    M1 for correct calculation of 'one' combination of 2+2+2
    M1 for correct number of times each probability is timesed by
    M1 for correct addition
    A1 for evaluation
