<p>Well, correctly is perhaps a more loaded word than I meant to use… I don’t mean anything very complicated. At OSU, you can usually take 3 or 4 normal-credit-hour classes a quarter. I think most people opt for 3.</p>
<p>If you take 4 each quarter you can get in an 3 extra classes a year without too much difficulty, with adds up to 12 extra classes (over a year’s worth of 3-class quarters) over 4 years. That would be pretty tiring if they were all difficult classes, though, but it’s kind of nice for electives.</p>
<p>I think on the semester system it would be more burdensome to fit all of those classes in (one semester you’d have to take 2 extra courses, after all.)</p>
