Sixth form

So basically I go to an all girls grammar which gets you really good grades, however it is very uptight and not very exciting. I want to join a mixed sixth form- also a grammar, but I obvs won’t know the teachers and won’t know the students. Which should I pick?

Is location problem? First, think about what A levels you want to pick. As some schools may do a certain language, or do economics, law… (my school didn't offer those )
