USC's current articulation agreements with California Community Colleges are available by geographical region and by college name here:
After you've selected a school, you will see a list of courses which meet USC general education categories and other core requirements, USC course equivalents, and all transferable courses. Courses not listed in the agreement will not transfer.
You can also use this Transfer Planning Guide (TPG) which helps applicants choose courses from a specific transfer college before attending USC. Once you identify the transfer college and your desired major at USC, the TPG will display all the requirements for the USC Core (General Education, writing, diversity and foreign language) and the major you have chosen. Under each requirement, the TPG shows which transfer courses taken during the 2014-15 academic year at your transfer college will satisfy those requirements.
If you plan to transfer to a four-year college, you should meet with your community college counselor as well to plan the classes and schedule that you need to stay on track. And we've also written a couple of articles about charting a successful path through community college that you might be interested in. Best of luck!
