Thanks for your replies. It looks like it's any 12 courses, which would mean a Sim could take several electives.
@Stormkeep I might do only one course in a term again, so I can have my Sim go out for a team. After that, I'm not sure what I'll try. I play The Sims to relax and unwind, so the thought of taking several classes and having to carefully plan out a schedule seems like more work than I'd care to do right now.
@Elliandre I'm finding that with one course, it's easy to do anything I want. I have time to let my Sim hang out on campus and socialize, join campus organizations, and still have plenty of time to make high grades. I'm thinking a second degree might be fun to do, since it requires fewer credits. DU is a lot of fun!
