<p>squadus, you’ll have to take a certain number of units for GE (if you are in TO there are an equivalent number of CORE units) plus two theme courses (unless you place out with AP exams) plus 12 units of language (unless you place out with AP or a placement exam at USC), plus a proscribed number of units in your major, and if you want a double major, or a minor (or two), there are required courses (and they add up) so you’ll have those units, too. To graduate, you need a total number of units (is it 128?) and that means after satisfying your major(s), minor(s) GEs and such, you may be short some units and those are elective units, taken from whatever department you choose.</p>
<p>Most kids don’t need their AP earned units since they have so many classes they need or want to take anyway. But for the dedicated student who wants to graduate in 3 years, and only takes one non-demanding (unit reqs) major, it’s possible to use the AP units to fill out the 128 unit required.</p>
<p>Clear as mud? LOL.</p>
