Self-paced classes can be started at any time and can be done as slowly or as quickly as you like as long as you finish within 10 weeks. This is a completely independent study option with no interaction from other students. Paced classes have weekly due dates built into the course structure. You will have 8 days to complete each lesson before moving on to the next module. Interacting and getting support from the instructor and other students is available through the discussion forums. Both types of courses are online and can be accessed 24 hours a day, 7 days a week. To find out whether a class or self-paced or paced, read the course description.
