How do I excuse an assignment for a student in the Gradebook?
As needed, you can use the Gradebook to excuse a student from an assignment, discussion, or quiz. You can also excuse a student from a group assignment. Excused assignments are not calculated as part of a student's total grade.
When an assignment is excused, the assignment page and the student grade page will show the student that he or she has been excused from the assignment. Students cannot submit excused assignments.
