Check with an adviser of the college you'll be attending. Each college has different but the same basic requirements. Are you going through a 2 or 4 year course? It's just best to ask the registrar at your college. If they don't give the answer, they can direct you to someone there that will.

You will need to get all of your sciences out of the way first. Biology, Microbio, Anatomy&Physiology, Chemistry and do Algebra as well. Other basic classes will include english, psych and other electives. Getting these classses will give you a leg up and tend to be a predictor of how you will do in the more advanced courses.

Every state and college have different prerequisites, but they all have these courses in common:
English Compsition 1 and 2, Public Speaking, College Algebra, Anatomy & Physiology, Microbiology, Statistics, Chemistry, Nutrition, Pathophysiology, Clincal Pharmacology, Psychology classes, and there will also be humanities and electives that you'll need to take
Depending on whether you go to a private religious school, there might also be some theology classes that you'll need to take.

you need these courses:
1. Microbiology
2. Human anatomy
3. Chimistry 1
4. Chemistry 2
5. Mathematics
6. English 101 & 102
7. Psychology
8. Statistics
9. Physiology
10. Sociology

Good luck.

You must take two english classes, A & P one and two, and two chemistry classes. Oh and a basic math class.
