At CC, there is a general education program that many people (myself included) follow, called IGETC. It’s easy to complete in your two years, just make sure it’s done. If you have AP test units, that can probably knock out some requirements, which is always great.
And yes, it’s really best to complete all GE’s. I think there are some other requirements to be done before graduation at UC’s, but I’m not really familiar with them.
