<p>It is likely your advisors will limit you to 100 and 200 series courses your first semester. If you enter with max AP credit (32 units), you can probably start taking upper division (300 and 400 series) courses your second semster - assuming you have any pre-reqs. In general, 300 series are aimed at students with junior standing, and 400 series at senior-standing students, but there is a lot of crossover. (500 and up are grad courses.)</p>
<p>What is your major? Most majors have a foreign language requirement through a third-semester college course, but there are several that do not. Scores of 4 or 5 on an AP language course can waive the third semester, and for those without the AP waiver, many students with 2 or 3 years of foreign language in high school place out of the first two semesters by taking the USC placement test (part of your orientation homework) and only have to take the third semester at USC.</p>
