Out of each option, which you you choose?

Those options actually wouldn't be too bad for me because I'd still be able to do 3 of the subjects I chose- history, English lit and French- but I'd have to do ICT instead of sociology, which would be a bit annoying. I agree that they're ridiculous though. At my sixth form, we just wrote down what subjects they wanted to do and a timetable was drawn up to accommodate as many people as possible. Anyway, if you don't want to change schools, some arguments for not doing ICT could be that no other school or college makes it compulsory, it's a lot of work because it's so coursework based, it doesn't interest you, it's not relevant to what you want to do in the future, unis see it as a soft subject and because you're the only one who wants to do music, it could be moved into the same block as ICT so you could do maths. If you don't have any luck, see if your parents do.
