How Do I Delete A Student's Quiz Attempt.
First go into the course inside Brightspace and click on the Quizzes tool in the NavBar at the top of the page. When the page opens up with the list of quizzes, you will select the drop-down menu next to the title of the quiz. In the menu, select Grade.
When the page with the list of students and attempts opens up, you will find the student's name in the list, select the box next to their attempt and then at the top of the page, select reset.
A pop up window will appear asking you to confirm the reset attempt, which deletes the attempt and data. If you are sure you want to remove the attempt, select Yes.
