How do online courses work, exactly?

We've made it really easy to sign up for courses. On any course page, click the enroll button to register for a course!

Online courses have lectures, assignments, quizzes, and exams. You'll also be able to talk to other classmates through discussion forums.

To make sure your classmates are all on the same page, many courses will run on a fixed schedule. Those courses have a set start date (usually several times each year) and have due dates for homework, readings, and tests.
