Out of the subjects I "chose" I took:
History (A)
French (A*)
Music (a year early - A*)
Geography (A)
Single ICT (as opposed to double, urgh - A)
History, Geography and ICT were my only As in all my subjects, which of course is not bad, but I wish I had taken Spanish instead of Geography.
This is because I became very interested in French very quickly (I do A level - see sig) and also Latin (for "fun") and I think if I had taken Spanish I would have done a) better and b) enjoyed it far more because I HATED Geography. Lots.
But now I'm doing A levels and really, apart from restricting which ASs one takes, they really matter very, very little, even in applying for university. So it's no big thing.
