You can set an end date on a quiz in the Add Extras page while you’re assigning it. Or, if you’ve already assigned the quiz, you can click on Actions and then Edit quiz details to change it.
Once the end date has passed on a quiz, the quiz will continue to show up on students’ pages.
On your results page, the student's name will appear in red. You'll also see an L in the "Late" column if you're on the Detailed View. A student is late if their first attempt was completed after midnight of the end date, or if it's after the end date and they haven't completed any attempts yet.
Hover over a student's name to see when they completed the quiz. This information will be included when you download the quiz results.
