    Do not presume

    Many students assume that online classes require less work and are easier than traditional classes. In reality, online classes are designed to be just as rigorous and demanding as traditional courses. Be prepared to do a minimum of six hours of work a week in an online course and thats a modest estimate. Some weeks and some entire classes will require far more than that, especially during the weeks of finals and midterms.
