I was waitlisted by UCSD. Are my chances from getting in UCB or UCLA or even UCSB farfetched?
No.
Well, it really depends. Even different UCs look at different things; one of the things that Berkeley pays attention to is involvement in academic extracurricular programs, especially depth of involvement and those hosted by UCB.
I also got waitlisted, which I find interesting considering I was outright rejected to Davis. My stats aren’t great, but I had the opportunity to submit an amazing letter of rec to Berkeley, so I think that I might have a chance there come the 31st. But all in all, everyone is different, and depending on your major, I wouldn’t completely write off any of those schools.
