I also got waitlisted as a computer science major at UCSD with very similar stats (UC GPA is just slightly higher). Also had an internship in computer science. I was rejected from UCSB, UCLA, UCB (and some other non UC colleges). I did get an acceptance from UCSC, and UCR with honors in the very beginning of March. I SIR’ed to UCSC and plan on accepting UCSD if I get an offer off the waitlist under my major.
