Year 12s: what will be the first way you research your future options? >>

Uni choices - bit stuck!

i thought i’d finally made up my mind about what type of course i was going to apply to for 20/21 entry, but i’m stuck again :/
i really love music and probably want to end up composing&producing later in life, but i really love the idea of taking criminology at Uni too.
i’m really torn because i’m really passionate about prison reform and learning about how society creates criminals etc, but at the same time lots of people are telling me that i should do music...
my sixth form doesn’t offer criminology as an A level so is it reasonable to do it as a degree but then do music stuff again later on?? i also really love one particular Uni’s CrimSoc department- it looks amazing

(sorry this was long i’m just very confused and stuck - any advice will help)
