Students of online courses usually have every convenience at their disposal to complete their degrees. Classes can be viewed online, on television or on videocassette. Some schools offer these options to allow students to choose the method that would work best for them. Each course would have required reading from textbooks or study guides. Using online technology, students could have class meetings virtually, online discussion groups or chat sessions with other students or the instructor. Communication could also be performed by e-mail for assignments and testing. Instruction could be viewed on videocassette in the students' homes at their convenience. Instructors and advisors are available to assist students to stay motivated and self-disciplined to finish their degree.
