On this page you can purchase selected self study classes for $50 per class. When you buy a self study class, the lectures will appear directly in your library, under the "Self Study classes" heading. Self Study classes do not have the forums. You will not have any access to the course instructor for questions or feedback.
You will have access to these materials in your library for one year from the date of enrollment. You can keep your library pass current by enrolling in at least one course a year. Alternatively, you can purchase a library pass for $50 per year for as long as you wish to have access to prior class materials.
