Wow great stats for UIUC. They say they hold 100 spots for instate students. You need to perfect his essays for UIUC.
Nowhere near UIUC caliber, University of Alabama Huntsville is a near automatic full ride https://www.uah.edu/admissions/undergraduate/financial-aid/scholarships
University of Arizona good for merit and CS. You’d get an automatic 35k merit scholarship a year so your final cost would be 16k a year.
