32 ACT or the SAT equivalent seems to be a magic number for unlocking some big merit scholarships, as long as you keep your GPA as close to 4.0 as you can. 33/34 and up, even better.
Nebraska. punch in some numbers. i think a 32 would get you enough for tuition.

Alabama, Alabama-Huntsville, and Ole Miss pop up frequently around here for their generous auto merit.
Ohio State is a great school and might be affordable for in-state.
Minot State would probably be affordable without any merit aid. in the same vein you could look at South Dakota, South Dakota State, North Dakota, North Dakota State
high GPA + ACT/SAT is the key to many great merit possibilities.
of course if you crush the PSAT that puts you in great shape.
