Had like a 3.3 GPA but with a lot of extra curricular activities volunteer work, club leader, soccer team, community service, AP classes, ect.
ACT: 21
SAT: 1450 
Strange. I had a slightly worse GPA, but better exam scores, yet I was rejected from CSULB.
CSUs are making some really arbitrary decisions. It seems like there's no longer a standard. Their semblances of standards are pretty unfair, to be honest. Congrats on the acceptances, though, and I wish you the best of luck with the other schools, my friend. I, myself, am also waiting on UCI, so hopefully that pans out.
got into UCSB ! 3 for 3 so far.
Nice, brah! Where else did you apply aside from UCSB?
