I'd be really interested to know if there is a way to undo an attempt. This is becoming an issue for us. I advise staff to lock the student's submission when they inadvertently allow another attempt and to add a comment in the feedback comments area, but it would be neater if you could undo the action. I've added a screenshot of how it appears in the grade book with another attempt allowed but with submissions prevented/locked. We are on Moodle 2.9.
