Alabama has changed its out-of-state scholarships, so that a student needs a 3.5 HS GPA and 36 ACT or 1600 SAT to get the full tuition scholarship. Even then, the highest scholarship only includes one year of on-campus housing, so it is not a full ride. Note that if parents are uncooperative, the OP will not be able to borrow either federal loans (requires parental FAFSA) or private loans (requires cosigner, usually parents) to help cover the rest.

Some actual full rides, including tuition, room, and board, are among those listed here (verify on school web sites in case they have changed):
