I know a few posters have talked about looking for scholarships. Some caution though...remember that a majority of these outside scholarships are one-year only, and in many cases only incoming freshman are eligible. You may find enough to meet the gap for freshman year at the school of your choice, but realize that you may very well need to make up that amount on your own the next three years.
Many schools that offer big merit scholarships have VERY early deadlines...as in November and December of your senior year. Miss those deadlines and you miss eligibility.
Finally, PAY ATTENTION TO FINANCIAL AID DEADLINES! I can't tell you the number of times I've read on the College Confidential message board how kids have missed the priority deadline for financial aid and wonder if the school will make an exception. The deadlines are there for a reason: if you want the best chance at the most aid, make sure you get your applications and paperwork/filings in on time!
Do you mean apply to the colleges this early or fill out their financial aid info before you fill out the FAFSA?
