Seems like University of Arizona and Arizona State University may be worth a look as potential safety candidates, with automatic admission at a 3.0 HS GPA and automatic scholarships based on GPA, GPA and SAT score, or NMF status, while having reputable math departments. UA is just at $60k for out-of-state students, but automatic scholarships should bring the price down. ASU seems to be a bit lower priced, and also has automatic scholarships. Note that “National Scholar” includes NMF when you are looking at their scholarship listings.
