Changing quiz review options in my moodle

This from my customer recently.

In bla blas's Music Theory (Basic) course, the student is not allowed to review quizzes that are completed.
 We have allowed this in the past, right?
 Can we turn on review?

Upon further review the settings for each of the quizzes in the course were set like this.

Got it?  only the marks where set to display after the quiz and later while stile open.  Not much feedback.  I thought the teacher must have set them, but that was not the case.  Makes me wonder how they got this way?  Anyway.

I was able to turn on more review feedback immediately after and later while still open.  I had to first, click the attempt option, which then enabled the other options beneath it.  This was not entirely obvious to me at first.  I think I tried clicking on the other options first, to no avail, looked around the room and probably said some profane words ;) - but, I did eventually figure out what to do.

Moodle quizzes are very feature rich.  A real strength to the platform.  Compared to others, it has more capacity, more options and consequently, more confusion.

I was able to change the setting for each of the quizzes by turning on editing and going to the quiz settings.  Not the quiz itself, but the settings for it.

Also, I went directly into the DB and pondered updating it there, rather than through each quiz one at a time, but I ended up just using the interface.

The end.
