@abcde11 - UC’s do not accept transfer credits for clep. See 2nd page re: transfer credits, clep and max credits -http://admission.universityofcalifornia.edu/counselors/files/Transfer_Credit_Practice.pdf or you can do a google search. The CSU’s do accept clep, under certain circumstances, and you have to check each CSU individually.
You can take classes at other California community colleges and they will transfer over, however the CC you plan to get an AA/AS (if that is your goal) may require x number of credits from their college. It’s fine for a few credits, but not when you are getting roughly half your from one CC and half from another.
