Take care with this online service. Though it is inexpensive and offers a wide variety of classes, the quality is not up to snuff.

The lesson plans are replete with grammatical errors and typos. The feedback on assignments is non-existent ("You have scored 25 out of 25 points)  or superficial at  best, e.g., "Good summary" and "Well put." Exactly how you aren't told.  Sometimes you have to wait weeks before getting grades.

The quizzes, which are laughable at best,  have information that is not in the lesson plan. The assignments require little more than a restatement of the lesson plan, and in most cases the students are not even instructed to use outside sources.

You'll be better off with Coursera, which offers free classes from a number of heavyweight colleges.
