You can reset the quiz via the platform yourself!
All you have to do is go to the quiz page and click on the purple button “Reset Quiz.” If the button isn’t there yet, check to make sure you’ve waited 24 hours after your first time taking the quiz! The quiz cannot be reset until 24 hours have passed. Keep in mind that you can only reset a quiz one time, so it’s worth taking a look at the questions that you got wrong before resetting the quiz.
