Joan Spitrey is absolutely correct, and those prerequisite courses are definitely the place to begin. She is also correct in saying that contacting individual schools for their specific requirements would be smart.
Can you clarify if you have a high school diploma, and if you have already had some college experience? If you've taken college courses, what were they? If some were biological sciences or math, that may count towards some nursing prerequisites. If you'll be starting your nursing studies without prior college experience, there will likely also be some language, psychology, and other requirements, as well, just like Joan suggested.
Visiting the nursing department of schools in which you're interested is a good idea. You can meet with an advisor, review your previous educational experiences, and determine what the next steps should be.
