Sometimes a Mute icon will appear next to an assignment when you review your grades.
Note: Students can still see and submit a muted assignment.
You can access your grades by clicking the Grades link in the global navigation or the Grades link in the course navigation.
A muted assignment appears with a Mute icon in the Score column. This icon indicates that your instructor is currently working on grading this assignment. While your assignment is muted, you will not receive notifications about grades or submission comments. Your grade will become available after your instructor finishes grading and un mutes everyone's assignment.
