In AI paragraph answers, allow/force students to keep resubmitting answers, while time allows, in order to improve grading. Points would be calculated according to the number of retries it takes to get to higher percentage. This would be much more preferably than the current method of only allowing a single submission and getting them to play the 'clicking on sushi' game while they wait for the next game.

In self-paced mode, re-present low-scoring multi-choice questions until students get them.
