I think the teacher student ratio is the best thing about my school. The students can get more one on one time with the teacher helping them understand the work better. Having such a small class makes it easier to adjust from the transition from highschoool to college.
The one on one interaction you receive from the instructors. In other institutions you can run the risk of just being a number, but when you have smaller classrooms the instructors get a chance to work with you more.
