CS is one of the most competitive majors at all the UC’s and your UC capped weighted GPA is below the averages although your SAT score is very competitive. UC admissions tend to be very GPA focused but they also look at your EC’s and essays, so it is not just about your stats. Every UC is looking for something different in their applicants and also if they “fit” into the campus.
A waitlist is not a rejection so opt into the waitlist if UCD is a top choice but move on and get excited about the other schools that have accepted you since you will need to SIR to another school before you hear from the waitlist.
