What are chances for getting direct admission to UC CS programs directly with 1530 SAT (800 Math)?

Assuming the GPA math comes in at 4.1+, you will be competitive for all the UCs. The top 3 will be a little stretch (maybe 40/60 odds) , but your ECs and a strong essay will help you stand out.

I should add that there is a lot of subjectivity to UC admissions so, they can be unpredictable Apply broadly.
I’d add SDSU to your ap list as a safety.

Good luck.
