Talk to the admissions office at whichever school you are interested in. They will give you a list of pre reqs. Most commonly you will take an English course, anatomy and physiology 1 and 2, microbiology, intro psych, developmental or human life span psych, intro sociology, some sort of math and sometimes a chemistry course.
go to the website of the school your are interested in. The program / majors usually list what thier prerequisites are. You want to take prereqs at the same school you are aiming for nursing as frequently schools prefer thier students over anothers schools. Good luck. Figure out finances too as many nursing students try working FT and end up failing out because too tired to study. etc
Each school has different prereqs: ex: chemistry, A&P, english of sorts, math, etc and etc
