What does an hour of college credit mean?
For colleges and universities that operate on a regular two semester academic year, one credit hour means one hour of classroom time per week. Most courses are three credits. Thus, you are required to be in class three hours per week. Some three credit courses are broken down where they meet three days a week for one hour each day, some meet two days a week for an hour and a half, while still others meet once a week for three hours. If the course is four credits, then you are required to be in class four hours per week etc. This should not be confused with study time outside the class room. The study time will depend on whatever it takes to get a good understanding of your subject content and class assignments.
