The Question Library is a good place to store, organize, and easily access all your questions within a course.
Import questions into Question Library to consolidate questions created with the Quizzes, Surveys, and Self Assessments tools. Consolidating questions within Question Library enables you to efficiently transfer questions to new courses using the Copy Course Components feature. You can also import questions from a CSV file or a learning object repository.
When you import questions into surveys or self assessments, the answers from the Question Library, point value, and difficulty indicators are automatically removed.
You cannot import Likert questions to quizzes and self assessments because they are unique to surveys.
