4. Scroll all the way to the bottom of the page to the Course Pacing section
5. Select Self-Paced

IMPORTANT: A course's pacing cannot be changed after a Course Start Date has passed. If you wish to change your course's pacing after the course has been released, you'll need to first adjust the Course Start Date to some future date, then change the pacing as outlined in this doc. 

See the second item in this doc for how to change a Course Start Date.
