University of Arizona does not appear to automatically admit with 3.0 HS GPA like it did previously (and even then, some majors may have required competitive admission). See The University of Arizona . Note that it has early action, so apply during the early action period if interested. See Types of Aid: Scholarships | Office of Scholarships & Financial Aid for scholarships.
Arizona State University is more transparent in admission (see First-year admission requirements | Admission | ASU ) and to each major (find a major at Undergraduate Majors | Degree Search | ASU to see if it has additional admission requirements). See | Financial Aid & Scholarship Services to estimate scholarships.
