I can only speak for the following:
UCB - EECS is direct admit; L&S requires 3.30 in 3 select CS classes before you can be admitted
UCLA - EECS is direct admit
UCSB - CSE is direct admit
UCD - I believe that both CS and CSE are direct admit but I heard from someone else that CS may not be.
I thought I read somewhere that UCSD CSE has a 3.3 requirement but I could be wrong. I think UCI’s CS programs are all direct admit but I could be wrong. Pretty sure that all the other UC CS programs are direct admit.
The most important thing for admissions evaluation is your GPA, so without that there’s no way of knowing your chances. Unless you’re being recruited for tennis, chances are that your championship will be treated as a nice EC.
