I graduated from UC Davis that runs on a quarter system (actually, almost all UCs except UC Berkeley and UC Merced runs on a quarter system).
Pros:
- if you hate a certain professor, you don’t have to be stuck with them for long
- ^ same applies if you’re bored and sick of your class after a month
- you get to take more classes because each term is short.
Cons:
- because the term goes by so quickly, you might not have time to digest what you learned. This can hinder you if you’re not a fast learner.
- more stressful because you’ll have tests and quizzes almost every week (at my school, some people esp. those in certain science courses literally had MIDTERMS the day BEFORE finals)
