Update cards of quizzes, unit tests, course challenges

Hi Khan Academy! For your new mastery view, please revive these old cards before and after quizzes, unit tests, and course challenges. In fact, all practice cards must show what skills a student is taking, what level they're at currently, and the end-of-test card must have a "re-take test" button. I'd even love a loop the test button, that lets you practice like the missions: super-helpful in Course Challenges for a brand new course one knows well already.

I don't like the oversimplified cards that were made as part of the update I'd linked to, and given your new mastery experience provides more context, I'd love to see the old cards back. But in the new design language, with the playful doodles and smiles! Please do consider this request as you expand the mastery view to non-US regions. These detailed test cards can be implemented to all courses and regions I hope, at least Math.
