Overview :The Question Library is a central repository that stores and archives questions which you can reuse within a course. You can create multiple collections within the Question Library to organize your questions by type and topic, making it easier for you to find questions for your quizzes, surveys, and self assessments.
As a best practice for storage, organization, and easy access, we recommend that you create all your questions using the Question Library. You can also consolidate questions created within the Quizzes, Surveys, and Self Assessments tools by importing them back into the Question Library.
