I am currently in the Lower 6th at sixth form. I am taking 5 A levels: Maths, Further Maths, History, English Literature, and music. I'm also doing STEP maths in general studies. For GCSE I achieved 10 A*s and 2As (which may change subject to remarking). The only thing I am decided on is that I want to do Maths or Music at Oxford, Cambridge, Durham etc. or other very top universities (I think my GCSE grades will enable this). However I am really stuck as to whether to do music or maths! I've always been good/interested in maths, and got an A^ in further maths GCSE. On the other hand I play the piano, the guitar to grade 8 standard, and the bassoon to grade 7. I also have music theory at grade 7, and I'm a pretty advanced composer (my favourite being fugues).
Does anybody have any suggestions/advice/help?
