i think music is one of the more popular subjects, so getting into a prestigious uni like york, which also has one of the best departments in the country, will be tough. york also want grade 8 theory before you start the course tho - this is putting me off, because even tho the exam wont be a prob, i hate doing theory and i get the impression the course is full of it! most places want an A in music A2 too. if youre really good at performing try a conservatoire, i dont know how good you have to be, but i did my grade 8 in april and im being told to apply, since theyre outside of ucas and so you might as well!
