Hello dear Khan Academy-ers and Site Moderators (if you are one of course),
I request that on practice/tests (quizzes) and the unit test there is a "restart" button. I was thinking that what's the point of getting 50% or less and still finishing the practice/test? Because you didn't meet the minimum requirements of the practice/test (50<) and so you fail the practice/test and lose mastery points. So all I ask is that there should be a "restart" button, so that when you go "Oops! I didn't meet the requirements for this practice/test and I know that even if I get 100% on the rest of the questions, I will still have failed the practice/test.", you can just say "Hmm... I'll just restart this practice/test." and press the "restart" button.
Thank you for reading and have a Funtastic day.
NOTE: Sorry if I said "practice/test" too much
