I have a professor who asked for the ability to just show incorrect answers in a quiz. He is making video feedback to students, and he would love to be able to apply a filter to just show incorrect answers. He knows his students only care to see feedback on the incorrect answers. He would like to filter or limit what he and the students can see, if they choose.
I do wonder if this feature could be wrangled into Quizzes.next either under moderate or speedgrader.
