The UCs calculate and use all three GPAs, using the course information that you give them in the application.
For example, you can look at this page from UCLA that @Gumbymom pointed you to. It gives stats in terms of unweighted, and fully weighted GPA. First-Year Profile — Fall 2025 | UCLA Undergraduate Admission
A fully weighted GPA of 4.73 is very high, so if that is accurate, it should help you at the selective UCs. But they are looking at a wide range of holistic factors, so admission can be difficult to predict. Good luck!
