Nice people here, how can I repeat all the challenges that I have done so far?
You are welcome to go through the challenges as many times as you like. If your previous code is still visible in the editor, you can click “Reset this challenge” to clear the code back to the original boilerplate.
If you are specifically wanting to clear all of your progress (remove the completion checkmarks), there is an option in your account settings to do so. Understand that this will reset your certification progress as well.
Thank you very much.
