Transfer from the University of Arizona to a UC or CSU as a junior.???!

I am currently going in to my sophomore year at the UofA and I am hoping to transfer to either UCSB, UCSC, Cal Poly Slo, or another highly ranked uc or csu after this year. I have found that the uofa is not for me and I am going to do my best to transfer. I was wondering if anyone knew if there are the same requirements to transfer as if I were to transfer for a community college? I have a 3.1 GPA and I have 3 A’s, 5 B’s, and 2 C’s and I have completed all 32 of my attempted credits. If I were to keep going at the same pace what are the chances of my being able to transfer to a UC or CSU by my junior year? If anyone could please help!! Thanks!
