<li>Most people take four classes or 16 credits. Some combine smaller classes to achieve this number.</li>
<li>Yes. You aren’t “required” to take much unless your major requires it because even Gen Eds have some choices fro each category. But it may take longer to graduate if you stray off your major too much… If that happens in a particular subject, I’d suggest double majoring so you get something out of it at least.</li>
<li>Yes and no. Classes aren’t scheduled based on freshman in the mornings etc, but you do have the last pick of courses so the choices that are left may be morning classes. Trust me, if you don’t want morning classes, more likely than not, you will not have to take them.</li>
<li>Depends on the major/class/prof/TA</li>
