Suggestions: Missed Questions Summary
At the end of a lesson/practice it would be nice to see the questions missed and their correct answers, to better remember them next time.
I would actually really like if the questions were asked once again at the end of the lesson (probably optionally). So close to having just seen and failed the question, it is close enough that you are likely to have the correct answer fresh in your mind, but it still forces you to fetch it and help internalise it a little more. It's a little thing, but I think it'd be helpful.
So pretty much agreed. :)
