Online courses allow you the flexibility to be home and study to get your grades for people who do not do well in a classroom setting, need to be home with family, or who does not have the transportation to make it the classroom daily. The workload is hard but accomplishable. Registration is easy, you can register yourself or let your advisor register you. The professor/student relationship is strictly on the professional level with the advantage that the student is successful in their classes. You form new friends with your peers and began to form study groups.
