Hi Ben,

After you've started a quiz, there is not a way to restart the entire quiz without first completing the remaining questions in the current attempt. This is intentional in order to encourage practice and repetition, as well as to foster a growth mindset. Ultimately, we believe it is more important to learn from mistakes and to focus on practice and improvement, rather than on the 100%.

I hope this helps! Please let me know if you have any additional questions!
