Hi Glenys,
yes, that explanation looks very clear. Nice job!
Maybe your students would prefer if the delay at the end of the quiz (a.k.a. "Delay 3") setting for this quiz was changed to "Do not continue automatically"? Then they could browse around the quiz freely after the quiz has completed. (The results are returned to Moodle silently in the background.) Although, if the quz is in a long chain, it may be difficult for the student to work out how to continue.
regards
Gordon
