<p>i would consider 3 maybe 4 classes in the quarter system reasonable. but i dunno how this works for the semester system. what's reasonable at berkeley?</p>
<p>Most undergrads take 15....UNITS. The minimum is 13. The max is about 20 (usually.) People can go under or over if they have good reasons for it...</p>
<p>Most first year students are recommended to take 13-15 units. The maximum is 20.5 units in Letters and Sciences. In order to graduate on time, you need to take an average of 15 units every semester, though AP units and others play a factor in alterating that.</p>
<p>how many is 15units? 5?</p>
<p>That depends. Most classes are 4 units, so 15 units could be 4 classes, one of which is a 3-unit class.</p>
<p>Lower division science courses are usually 4 units each, except Chem 3b which is 3 units for lecture and 2 units for lab. As long you take an average of 15 units per semester you should graduate on time.</p>
<p>I think its important to distinguish between the number of classes an units. You can take 4 classes and have the unit count be 20, or take 4 classes and have your unit count to be 8.</p>
<p>Most of the time, it's best to go by number of units rather than classes, at least in my own personal evaluation.</p>
<p>Most seminars are one unit, and some classes are two or three units. Four unit classes are the most common, and most intro language classes are five units. I agree with eiffelguy, worry about the units, not the number of classes.</p>
<p>it depends on the class. Units don't really mean anything, well from my experience in engineering. For example, I took an Ethnic Studies and a Sociology course that were 4 units each, and the workload was nothing.</p>
<p>Most mechanical engineering courses are 3 units, but the workload in some is way way way more than that. Engineers generally take 3-4 courses a semester, regardless of the unit number.</p>
