Build On Last Attempt: Scoring Options

Community Member

A student tried to make a 2nd attempt on a Quiz and was stuck on a spinning symbol "loading" page. It resolved and the student could retake the quiz after toggling "Build on Last Attempt" OFF. The grading was set to Keep "Average". I considered switching this to Keep "Highest" to see if it would resolve, because that's the setting I've seen others use for BOLA. However, I didn't want to affect other students' scores and bring about any confusion.

Is there a certain Keep Average/Highest/Latest that allows or disallows the quiz to open using the BOLA feature?
