You can view all your course assignments on the Assignments Index page.

Notes:

• Your instructor may choose to hide the Assignments link in Course Navigation. If the Assignments link is not available, you can still access assignments through your user or course dashboard, the Syllabus, Gradebook, Calendar, or Modules.
• Assignment Enhancements does not support the following assignment types: No Submission, Group Assignments, Peer Reviews, and Cloud Assignments.
• If the assignment you are accessing displays differently, Assignment Enhancements may not be enabled in your course or your instructor may not have used a supported assignment type. Please view this guide for more information.
