I would think that it depends on where you live as to how that would affect the class size, and teachers.

I went to a 2 year college many years ago in a very large city and found that the class sizes were small (30 or less) to large (30 to 50+) students depending on the subject matter.

I am also attending a 4 year year university that has a branch at the town I live in about 50 miles (one way) from the university. The classes that I attended there( at the branch) tended to be on the small size ( 15 to 30).

Hope this is of some help.

You will receive a much better and more thorough education at a 4 year school and you will graduate with a degree that gives you more job opportunities. 99% of employers will hire a person with a 4 year degree over a 2 year degree.
