I need 480 ums for A/A*. I would have roughly 1420 in total which is not enough for 3 A/A*'s.(Original post by DJMayes)
I think the ordering is as follows:
1) Obtain highest Maths grade
2) Rearrange/add to obtain highest FM grade without decreasing Maths
3) Rearrange/add to obtain highest AFM grade without decreasing Maths/FM
Thus in this case if there is an ordering which obtains A*A*B and one which obtains A*AA they would take the former but it is worth asking to manually cash in grades in order to obtain the latter and meet your offer, with your school and your uni.
...with these A Level results?
