How do I move a student into a different group?
You can move students within groups. However, changes should be made before assigning a group to an assignment.
If a student is added or removed from a group after receiving submissions, the submissions and grades may not align correctly. If a student is added to a group after the group submission, any re-submissions will overwrite the original submission; all previous grades will remain but the Gradebook will show the assignment was resubmitted since last graded. If you want to move a group member with a graded submission, you may want to clone the group set instead.
Open Group Set
Click the Settings icon , then click the View User Groups link . Or click an existing group set .
