<p>The UCs have minimum requirements which combine GPA and test scores to be eligible for admission (the higher the GPA the lower the test scores need to be), see <a href=“http://www.universityofcalifornia.edu/admissions/undergrad_adm/paths_to_adm/freshman/scholarship_reqs.html[/url]”>http://www.universityofcalifornia.edu/admissions/undergrad_adm/paths_to_adm/freshman/scholarship_reqs.html</a></p>
<p>That is for eligibility in a statewide context which applies to most applicants. They also have a top 4% local context rule where someone in the top 4% of his class is automatically admitted to a UC (although not necessarily one of his choice or major of his choice) regardless of test scores. They also have a third way to become eligible by simply having very high test scores.</p>
