Make sure you decide on what accomodation type you want (catered or self catered) because most colleges only offer one option and there are significant price differences. There’s a page on the website for accomodation prices.
I’m doing music too! I Initally just ranked all the colleges as close as they were to the department but then I found out that only St Cuthbert’s has self catered and choral scholarships. There’s also a college guide too and the offer holder open day has the opportunity to see 3 colleges.
