UCs don’t use standardized testing to determine if an applicant to any UC is eligible to receive the “Statewide Guarantee” – which guarantees a space at a UC campus if there’s room; they look only at grades for tenth and eleventh grade and they have a metric for A-G courses taken.
If you go into the main UC application portal & click on “How your application is reviewed” you’ll see if you/your student ranks in the top 9% & is thus eligible for this statewide guarantee.
