Clearing high scores
While it's not possible to reset the high scores for a set, there's a quick solution if you're looking to reuse a set with a different class or a new school year is about to start.
Simply make a copy of your set, then delete the original to prevent confusion. Your new copy will have a blank Scores leaderboard and won't show that any students have completed Spell or Learn.
Add your new set to a class or share the link with your students so they can begin studying and competing!
