I'm currently a year 11 student in a private school in the UK. I'm foreign, and I want to study music in Oxford University. I am expecting at least 8 out of 12 A* grades in a mixture of GCSEs and IGCSEs this summer. For A Level, would maths, physics, psychology and music be a good combination, or do I need an actual essay subject like English Literature or History? I am expecting an A or A* in both of them, but I don't think I would get an A in A-Level.
Also, are four subjects too much? My teachers are advising me to cut down to three (and we're not doing AS Levels due to the reform) because they want me to concentrate on building my musical skills. I don't want to give up any of the subjects (other than music which I have to do anyway), but I do realise it makes sense to concentrate on three and get the best results possible. I need AAA which I think I can achieve with reasonable effort during the next two years.. What do you think I should do?
