You can create sections to organize your questions into folders within the Question Library. As a best practice, we recommend that you create a section in your Question Library, then add your quiz questions to this section. This will make it easier for you to select the questions you want to add to your quiz, especially if you plan to randomize the questions on your quiz. See the Question Pools guide for more information.
You can also import sections from Question Library directly into a quiz, survey, or self assessment. Importing sections from Question Library will transfer section folders and all of their associated properties (section name, messages, images, or feedback).
Although you can create subsections within sections, D2L recommends you keep question organization simple and intuitive.
