Trying to transfer to a UC...

So i began my college career at an out-of-state 4-year institution, absolutely hated it and came back to california after a year. Im currently taking classes at a CCC and want to apply to UC davis(as a TAG), UC San Diego, and UC Santa Cruz for biomedical/bio-engineering. I have about 23 semester units from out of state(basically bs classes like poly sci, anthropology, environmental studies, history and precalculus). By the time im done with all the classes listed on assist.org and ready to apply for transfer to one of the UC’s colleges of engineering, i will have like 103 semester units from both an out of state 4 year and a CCC.

I’ve been reading many things that lead me to believe my chances are slim to none, especially for a TAG.
My overall gpa is currently a laughable 3.2(easily will raise it to a 3.4ish or 3.5ish by the time of transfer) and my concern is, is there much of a chance for me to get into these schools with all these units?

I would post in the UC transfer thread. Many knowledgeable posters whom can help you with your questions.
