If your instructor allowed one attempt, you can't edit your work after you submit. If your instructor allowed multiple attempts and you submit an attempt past the due date, the attempt will be marked late. Any attempts you submit before the due date aren't marked late.
Open the assignment. On the Upload Assignment page, review the instructions, due date, points possible, and download any files provided by your instructor. If your instructor has added a rubric for grading, you can view it. Select Write Submission to expand the area where you can type your submission.
Hover over the cell and click on the contextual menu on the right side of the cell. Then select the View Grade Details from the drop-down menu. On the following page, click on the Clear Attempt button or Allow Additional Attempt. Clearing the attempt will completely remove the student's first attempt.
From the pull down menu select View Grade Details. 4. On the screen that appears, find the submission near the bottom of the screen. To the right of the entry, click the button labeled Clear Attempt.
