In California, there are 32 public universities that should offer good financial aid to low income California residents. Have you checked their net price calculators? Are you sure that you cannot find one that you like? For even lower cost, there are community colleges that you can attend for the first two years, then transfer to one of the universities for the last two years. If you do not like large schools, you can look at CSUCI, CSUMB, HSU, SSU, and UCM.
If the net price calculators do not indicate affordability, you need to make a merit-seeking list. With a 3.85 unweighted HS GPA and 1770 SAT score indicated in one of your other posts, you would get a full ride at Prairie View A&M. You may get some of the other big scholarships, depending on your SAT CR+M score. A higher SAT or ACT score would open up more possibilities. See http://automaticfulltuition.yolasite.com/ .
