The Question Library is the central hub for all questions within D2L. Questions created within the Question Library can be imported to a Quiz, Survey or Self Assessment within your D2L course site. When building your questions for any of these tools we suggest doing it in the Question Library as it allows the questions to be accessible to any of the three aformentioned tools. Additionally, building your questions in the Question Library is the only way to get your questions randomized, since questions cannot be built in Random Question Sections.
You can access the Question Library from within the Quizzes, Surveys or Self Assessment tools by clicking the Question Library link at the top of the page.
