We ran into an interesting scenario: an instructor created a quiz with a question pool, pulling from the question library in a course A. Great! Then they copied the quiz only, not the question library into another course B.
The quiz copied just fine, and the pool is visible, but the questions are only (??) contained within the question pool?
#1 Courses are not linked — we were able to make edits to a question contained only in the question pool (course B), and it didn't prompt to update anywhere. The question was not updated in Course A.
#2 - Library > Pool can be relinked — copying the question library separately from Course A to Course B, did "re-link" the questions in the pool to the question library, but NOT questions that had edits. They still only exist within the pool.
#3 No direct import - You can't "import" from the pool to the question library within a course. Choosing the quiz with the pool as a source, shows no questions.
Where do the questions in Course B live?
I can see this becoming an issue quickly. Especially if instructors edit questions in a copied pool, but don't also copy the question library. Especially if they make edits. Is this a bug or expected behavior?
