1. Online courses are convenient.
The biggest advantage of an online course is that your classroom and instructor (theoretically) are available 24 hours a day, seven days a week. Your only excuse for missing class is not getting online! Otherwise, everything is available to you. You can get announcements, access notes, review assignments, take practice quizzes, discuss questions, chat with fellow students and study any time you want. Other than certain due dates, you make your own schedule for completing the requirements of the course.
