To randomize questions on a quiz, you cannot just add questions directly to the quiz itself. Instead, you need to place a Question Group inside your quiz and link it to an existing Question Bank. The group acts as a container that tells Canvas to randomly pull a specific number of questions from the bank for each student.
Note: This guide assumes you have already built a Question Bank in your course. If you haven't, you will need to create one and add your questions to it before proceeding.
Important: You must click the Create Group button (step 4) before clicking the main quiz Save button. If you just click Save on the quiz without creating the group first, Canvas will silently delete the group you just spent time setting up.
