The curriculum for each course is designed by the instructor. Each class includes extensive pre-recorded video content, some with a class workbook, access links to other available class media, contact information for your instructor, and community activities. The videos are viewable at any time, and they can be paused, fast-forwarded, and re-watched as many times as you'd like. In addition, many students utilize the class discussions below each lesson to share their thoughts and provide feedback on others' work.
