I recieved grants and a scholarship when I was in nursing school. When you apply for financial aid, if your income is low enough, you will automatically recieve grants in replace of either your subsidized or unsubsidized loans (can't remember which one). Then just check with you financial aid office and see what scholarships are available and how you apply.
I always go to my public library and look through the huge Mc-Graw, and college board scholarship and grant books to see if I can find any that are suitable for me. It helps to make copies of the pages with the scholarships that I'm most interested in. Good luck with the hunt!!
