Spread myself too thin in HS, what 2 study in college?

So in HS I took as many science classes as possible, but due to going to a bad HS I never really got the opportunity to go in depth with them. So basically I ended up at a pretty good STEM University because "muh diversity of thought". Right now I have equal interest and knowledge in physics, particularly electricity and magnetism but I know mechanics, the very basics of ochem, and a decent amount of bio. Math goes without saying ofc but I'm not brilliant at it or anything. Is there hope for a jack of all trades, master of none?
