Quiz Reporting Status Representation
I can't understand the difference between Quiz Reporting - Stats Representation = Incomplete --> Incomplete AND Incomplete --> Passed / Failed. See image:

I recently had a health and safety course that was set to user must score 99% to pass. Users had 10 questions with 10 points each.
System was set to record only highest score = ignoring fails.
But reporting was bringing back scores of 50 - 60 - 70 etc.
I think the setting was Incomplete --> Passed / Failed and when I changed it to Incomplete --> Complete the behaviour stopped.
Can anyone explain this logic so I might understand A: what is happening here? and B: how each of the 2 settings might practicably be used?
thanks
