I forgot to mention the add/edit Lesson page in MoodleDocs. I am tired, usually MoodleDocs is the first thing I like point out.
Max attempts (in Flow Control) deals with how long a student can be stuck on an question in a Lesson in an endless loop. The student has to get in the lesson first
. Once upon a time, I did not read the fine print and thought it was similar to the Quiz "Attempts allowed" setting, which does limit the number of times a student can take a quiz. My sites' SOP is to set max attempts to 1. We don't care about our adult students being frustrating by selecting the wrong answer many times, we want them to read and think about the material. So they have 1 chance to answer every one of our simple question correctly, or they "fail" the lesson and have to take it again. This tends to slow down the speed clickers.
Hope this helps.
