<p>Exactly, the professors may try to squeeze in as much material as they can, but you’d probably learn a lot more if you are in the class for 4 months than 10 weeks. Also, classes from campus to campus are probably different. I wouldn’t be surprised if a campus on a quarter system split the same one course on a semester system into two courses. The only real difference between them that is always true is that quarter system schools have more finals. Who’s to say that UCB’s classes don’t give you more work or teach you more material JUST because they only have finals twice a year? Also, the semester system probably allows professors to go deeper into the subject and it would ingrain the material into your mind better, because you spend more time on it.</p>
