If I start any course, I try to get mastery in it and unit test is required to get mastery or 100% score in that specific course. If I attempt any question of a unit test (say maths) wrong, I have to complete that test and take it again without mistakes to get mastery. Please add a restart button for unit tests.
I very much agree, this makes so much sense to have, and has been brought up time and time again by users since Unit Mastery was launched, like in the post below (which I suggest you vote up and maybe comment on). I'll pass along your request to KA staff, thanks for posting.
