When I add a question bank by importing a QTI file, it places it in quizzes and assignments, so the question bank is showing in the gradebook. I do not want this to happen. What should I do to remove these from my gradebook?
Can you tell us where the QTI file is coming from? It sounds like the file may contain both quizzes (which would show up on the assignments page) and question banks. If you don't want the quizzes, but only the question banks, you could just delete the quizzes. You would need to build a quiz to make use of the question banks anyways though, so maybe ou could modify the imported quizzes to meet your needs.
I've experienced this too, @RachelEtheridge, and I see that the QTI file ends up creating a quiz *and* a Question Bank. In the testing I did tonight, the quiz was unpublished. Deleting it from the Quizzes page does not affect the accompanying Question Bank.
