You are NOT expected to complete every module. You may pick and choose. You must complete at least 18 hours worth of content each week. This is about 3-4 hours each day.
The syllabus page shows a table-oriented view of the course schedule, and the basics of course grading. You can add any other comments, notes, or thoughts you have about the course structure, course policies or anything else.
