Keep lecture notes well outlined for preparation for the final exam. I would not take the Internet course because I need the extra communication around the subject. As focused as I can be on the subject, I absolutely require verbal opinions from the Professor as well as anyone else who is willing to share. This is the best idea for classes I have heard of yet. Especially for the busy life of a college student.
Internet classes are the key to the future in education.
Make sure you leave yourself enough time, and stay disciplined throughout or you'll suffer. I think the internet course is a good thing. But I preferred taking the lecture because of the interaction with you and the other students. I would tell them that they should be ready and work twice as hard as if they were taking the class in a class room. Procrastination will kill you so make sure you are not that type of student.
