Our child also got a Regents at UCI last year and was accepted to UCLA without the scholarship. He chose UCLA without any hesitation (passed up other Regents too) and is doing great there grade-wise. I doubt UCI will be appreciably easier, but that’s a bit of a guess. I feel like your decision is whatever UC you choose vs the full-ride at CSULB. That’s kind of a unique opportunity. I think what I’m trying to say is don’t be afraid of UCLA - you’re obviously smart and should do well.
