<p>I’m glad that you love the quarter system, but you aren’t portraying Berkeley’s semester system in an accurate light, much less any other symester system school that I am aware of. Here, few people (if any) take six full four unit classes. Very few people at Berkeley take more than 19 units in one semester, which is still considered a very heavy load. That would break down to about 5 4-unit classes (a 4 unit class being the most common around here) But here again we run into the problem of comparing units in two different systems. Basically, 14-17 units, or about 3-5 classes, is fairly standard, although this is no solid rule- some people take many one-unit classes and some take three five unit classes, for instance. Few take six classes unless the classes have much smaller unit counts, or there’s a lab attactched to a class, or something like that.</p>
