How self-paced study works
Courses are self-paced. There is no start date and no fixed end date, so you can begin whenever you are ready and work to your own schedule.
Each course shows an estimate in hours of how long it may take to work through from beginning to end. It is only an estimate; many learners take more or less time.
All the learning materials you need are linked inside the course itself. Some courses use a lot of video, others are mostly text, and videos are usually embedded throughout rather than collected in one place.
