yes. definately submit fafsa to any school you might possibly get into and be interested in attending. some schools have deadlines in the next few months. i would even contact these schools individually and ask what they recommend doing in terms of their financial aid.
Absolutely! The sooner you submit your FAFSA to your schools, the better your chances are of getting a good financial aid package. Even if you're waitlisted or not-yet-accepted, think of it as being proactive.
