I have some great news to share with you!

Based on the feedback you and many others shared, Khan Academy has launched a new feature that allows learners to start over an activity without needing to fully complete it first— it’s called the “Start Over” link! 

We hope you will enjoy this new feature, and welcome any feedback you have about it. Passion from the Khan Academy community helped bring this feature to life, and we truly thank you for sharing your thoughts about it. You helped make Khan Academy a better learning resource for everyone!
