it is a curse. Less material is covered and if you don't have a course in sequential trimesters, you have to spend more time reviewing. It is very impersonal and an assembly line approach to education

I prefer the trimester system. It allows students to be exposed to more classes. Less material may be covered, but it is not that big of a difference--material is just covered faster.

That depends on the faculty and the general attitude of the school.
