What classes should I take if I'm planning to become a nurse?

This is my schedule for my junior year (next year):
AP US history
Language Arts Honors
Pre-Cal
Physics
Peer counciling. (or should I take psychology?)

--
I already took chem and biology.

Do I really need physics?
What do I take if I DONT need physics?
I can't take AP chem or bio currently because of my CST scores.
