The 2 UC’s that emphasize the Fully weighted UC GPA are UCLA and UCB but all the UC’s heavily take into account course rigor/number of AP’s, DE, IB etc, and use the uncapped GPA on their website/UC website for statistical purposes.
Your GPA will not be evaluated within a vacuum since the UC’s consider 13 areas of criteria so take the courses of interest and do not worry.
