The California UC’s are test blind to your SAT/ACT score will not be used for admissions or scholarship consideration only for course placement.
The UC’s calculate their GPA based on the A-G course grades taken the summer after 9th through the summer prior to 12th. There are 3 UC GPA’s that are considered: Unweighted, Capped weighted and Fully weighted. Here is the UC GPA calculator and note as a non-CA resident, only AP/IB courses taken 10-11th grades will be given the extra Honors point bump.
