After my A levels i want to go to uni and study a sports science degree...however would i need to take a seperate science like biology along with p.e and another subject to do so ??
Biology, Chemistry and Physics would be helpful, but it depends on the uni if they make it a requirement. For example Bath would probably prefer it if you took Bio and Chem instead of PE.
I know someone who's doing Sports Science with PE, Photography, Business (and AS Design.) It's not a top uni though, so for a top uni I'd go for Biology, Chemistry, PE and perhaps AS Maths.
