Apply to MHC too :). On their part of the common app, they actually have a question about a sibling applying too, and may offer some sort of financial deal if the both of you get in.
Apply to more ‘merit’ universities.
Right now you only have Alabama as an affordable option. It’s a great university but you want to cover your bases, be able to compare financial packages.
(unless you meant UT Dallas? UT Austin admits very few oos students and doesn’t give merit. The strong stem school with merit is UT Dallas. For your stats I think you get a full ride at Texas State but I don’t know about deadlines.)
I’d recommend Truman State - strong academically, low cost, excellent scholarships.
Hendrix, Agnes Scott, Beloit would likely offer merit money but RUN THE NPC. Hendrix has a scholarship for your stats and has excellent academics.
What about Wheaton, MA?
Most importantly, don’t plan on community college : your act 32 and your GPA mean you can get full tuition scholarships* but if you attend community college you lose that money. You’ll save a little at first then pay way more when you must come up with total costs. Transfers typically get lousy aid. You’re better off taking a gap year than attending a community college.
Find ways to leverage your 32 act. Massachusetts doesn’t offer much in merit money but that’s not the case everywhere.
