I have a quiz where students must achieve 100% before moving to the next module. I would like to allow them multiple attempts with no time limit necessary.

However, if a student achieves 100%, the quiz still says 'Take the Quiz Again' even though they have achieved the maximum score. It does say 'Score for this attempt: 17 out of 17' but that is not clear enough and has confused a number of my students testing the course.

Any ideas?
