First, ask your question of the admissions rep or curriculum advisor that you're assigned to at the college where you go. That said, the first two years will focus on "General Ed" courses: English, History, Social Science, Math, perhaps some Sciences. You'll take some elective courses, too, such as art appreciation, foreign language, or music. For at least your first term, I recommend not taking too many units, because first-time college is a new experience and will likely require more attention, study, and challenge than you're used to. So if possible, start easy, "work into it", and you'll gracefully learn how many units you can successfully juggle. Best wishes in your studies!
