This very much depends on you and the course you are taking. Studies have shown that both students and teachers tend to spend more time working on courses delivered online when compared to the same course delivered in the traditional classroom setting. If you are not, at this time, comfortable with computers, some of your time will be spent figuring out how to carry out different applications on your computer. As a general rule, however, plan on devoting at least as many hours to online courses as you would to regular classroom courses.
