Are you a high school senior? Talk to your guidance counselor or a teacher with half a brain if you have one.
Did you submit a FAFSA?
Failing that, I'm sure there's a shit-ton of info at
http://www.studentloannetwork.com/ and elsewhere on the web, but I'm not even about to research it for you.
I paid for my school with a combination of workstudy programs, scholarships, grants, loans, and a bit of help from my parents (whose income and savings reflect quite a bit on your grant and loan eligibility).
