Follow these directions to delete a student's attempt on a checkpoint or a quiz:
Enter View Student Work (VSW) mode on your My Courses page or through the Profile Menu at the top-right corner of any in-course page. Click View Student Work for the student whose attempt you need to delete.
Note the icon in the upper-right corner of the screen that denotes the student view mode.
You are now viewing the Table of Contents for a particular student. Within the Table of Contents, navigate to the unit, module, and assignment you wish to adjust:
Click on the assignment to reveal the assessment. Under Student Attempts, click Delete attempt:
Confirm that you want to delete the attempt. Confirming the action will make another attempt available to the student (if the due date for the assignment has not passed). Note: This action is permanent, and a deleted attempt cannot be retrieved.
To exit VSW mode at any time, click the icon and choose Exit Student View.
