I teach CS Discoveries to multiple classes and when I do a demonstration to show students how to do something it saves the the version and I want to reset it to the original code for my next class so I can show them the same starting from the beginning. I don’t want to have to go and manually “undo” the codes etc. Is there a “reset” button? It would save me a lot of time. Maybe it’s been mentioned here before and I missed it. Thanks! ---

Hi @ereinitzer! Yes, there is a way to reset. You should see a ‘Version History’ button like in the image below: ![VersionHistory](https://us1.discourse-cdn.com/flex016/uploads/codeorgforum/original/2X/f/f6bab76b90fa4b819012611b03a939de82ba3110.png) After clicking on that, you should see: ![38%20PM](https://us1.discourse-cdn.com/flex016/uploads/codeorgforum/original/2X/d/db86d22c9bb0e6324dffe9e5920d94cf2a9ee232.png) Clicking on ‘Start over’ should reset the level. Hope that helps!! Let me know if it doesn’t and I’ll look for a different way cheers, Kevin ---

Hi Kevin, That worked! Awesome, thanks very much. ---

Version History works for Code Studio, but not for the quizzes. After I hit Submit during prep, the students are going to see all my answers (and my mistakes). ---

Hi @magendanzc, It would be cool to have the ability to clear students’ (and teachers’) quiz results to try them again. I’d recommend filling out a [feature request form](https://support.code.org/hc/en-us/requests/new) to make sure this is seen by the right people. Thanks, –Michael K. ---

Done. Thanks, Michael!
