I'm quite surprised that a uni such as Edinburgh has a 'BBB' as a typical offer for music and it's placed lower than expected in the league tables for music in most years. Why is this? What's the department and course like?
I don't know what the course is like, but I can tell you that league tables are based on so many different things they're not really worth much, and for many of its courses Edinburgh offers BBB, with the proviso that you have to be predicted at least AAA to be considered for a place. That's just how they do.
