On-Demand is a blended approach of both instructor-led and independent, self-paced learning. As a learner, you can find your own rhythm and you choose how fast you go. You have up to 1 year to complete the course, though there could be exceptions for extenuating circumstances.
The typical Module includes 20-60 minutes of reading (depending on your reading speed), and a multiple-choice quiz. After you complete these, you need to work with 1-2 StudyBuddies to discuss the module/quiz and do one or more scenario-based exercises. Each module will take about 1-3 hours of your time, and will require you to work with StudyBuddies (either someone in the course or outside of the course).
