As stated previously in another answer, the most unique feature is the courseware. The workload is flexible for even a busy adult to be able to devote time to their studies. If you can't attend a lecture, there are other options to receiving credit for participation/interaction. Registration process was smooth and if you're unsure about enrolling, you can request more information and receive a free two-week trial at no obligation. During the free trial you can see what it is like within the classroom and courseware. Professors are great and are available by email, some are also available by phone. In every lecture that I've attended there has always been an element of surprise/fun that makes it worthwhile. In the interactive classrooms, you can private message another student and exchange information for contact outside of the classroom.
