I got an average range for GCSE (A*A*AAABCC) and you can tell how I focused on some subjects more than others! I think that is what made the difference for AS (AAAB) and my predicted A2 (A*AA) because, whilst the work load is heavy having less subject really helps me organise my revision so I put hard work in all instead of just pretending that some didn't exist (sorry GCSE dance).
