If I'm enrolled in a CSU during the fall, and a CC during the spring, what will a UC see?

If you don’t take any upper division units at a CSU, you should be fine. @lindyk8 knows the specifics of this better than I do, though.

Are you sure that only 33 semester units will cross over? What UC’s accept may be different from what CC’s accept.

Try to follow the 7-course breadth for the schools you want to get into. Apply now to see if you get in anywhere, and if worst comes to worst, take another year at CC to decide upon a major, complete prereq’s, and so on. If you stay another year at CC, you can likely complete IGETC.
