Why is it not possible to edit a question in the question bank and it not then be updated in any quizzes that may have the question included?
This is very cumbersome to go back and find any quiz that was created and edit any mistypes or incorrect answers. The entire purpose of a quiz bank is to have everything done in one location.
Why do created quizzes not pool from any new questions added to a question bank?
All of this is possible as LMS systems such as Moodle do it.
