Thanks for the reply (and the PM from someone else. I am having trouble getting the PM function to work, but when I do I shall respond).
ElChapo, thanks for the confirmation. Does the UMS not directly correlate to the grade at A Level? I thought you need to achieve a total of 90% in the entire A level course to achieve an A*. I achieved exactly 90% in AS, so if I repeat this in A2 I assume that I would achieve an A*. I thought that if you achieved, say 100% in AS, you'd consequently be able to achieve less than 90% in A2, to still come out with over 90% overall (and therfore an A*) - is this not the case?
When you say an average of 90% in the modules, is that the case? So long as my total A2 examinations combine to equal at least 90% I should be OK (meaning that one of my exams can be slightly lower, and the other slightly higher than 90%).
