If you're a procrastinator like me you may have problems. I took one psychology class over the net and had a large course load that semester, so I didn't check in often enough. There was a discussion board that we had to post on three times per month, and a disk with quizzes over each chapter in the book. This class was offered at the university I was currently attending, so the class actually met twice, at the beginning of class and again at the end for the final. I don't know how that works if your class is in a different city or state.
Anyway, I got a B because of laziness but it was an easy class.
