I like the Keele campus but I live very near it and have been on various trips there as my school's connected to it- whilst I still would live there, I don't want to be so close to home! Especially since several teachers lecture there, two in the physics department...
Music? They do but it was in the same block as chemistry so I took that instead. I was going to do AS this year but then it clashed with physics
Were I choosing again I'd do music, but chemistry kept my options open more when I wasn't sure what I wanted to do, even though I've now dropped it!
Where else are you applying? You're the first Keele applicant I've seen!
