Unpredictable displaying of quiz from a question bank
I've quite a big issue for developers: the client asks for showing just 1 quiz randomly taken from a question bank in a unpredictable manner. For example: one time the quiz appears in the middle of the lesson, another time at the beginning or at the end.
The point is: is there a way to set the displaying of the quiz at an unpredictable and totally random moment during the scene? The aim is to check the factual presence of the user injecting interactive moments.
I have another one: once the user fails the single quiz in a QB, how to remove this wrong one from the same QB?
Going mad so far ...
