for transfers, UC admission is really curriculum heavy. If you don’t have what they see as the right classes, even a perfect GPA won’t get you in. I can’t really assess how you stack up by that measure. Coming from an unknown out of state private from which they dont see many aps, it is hard to say how they will evaluate your transcript.
Even many of the less selective CSUs are picky in the same way. It looks like Humboldt isn’t impacted for Psych so, they are your best shot.
Hoping it works out for you.
