If you’re able to satisfy the TAG requirements for your major at Santa Barbara or San Diego, there are virtually no public out of state schools as well-regarded AND are such a good deal. However, I’m not from CA, so idk about the difficulty of the TAG requirements: I would recommend talking to your HS’ guidance counselor.
Out of state public schools would be 50K + for a degree that’s not going to be markedly better (for the cost) than a degree from UCSB or SD, though again, that’s my opinion.
@Gumbymom knows a lot about CA schools and would be likely be able to help provide input on some in-state CA schools you should consider.
