What are the minimum and maximum amount of classes someone can take in college?

This usually depends if you are a full time or part time student, and could also depend on any scholarships/financial aid you receive. First, I would check the college website for specific answers. While I was in college, the minimum was 12 credit hours. Most of my classes were 3 hours a piece (english, math, science, etc), so I would usually have to take at least 4 classes. If you plan on taking additional classes, I would first consider the cost of these, as well as being able to handle the workload, so you don't overwhelm yourself.
