You can create a quiz by finding questions from Question Banks.
When you find questions in a Question Bank, you will see all of the Question Banks that you have built in other courses where you are the Instructor. You will also see Question Banks that have been added by your administrator to your sub-account, which makes it easy for instructors in the same department or program to share resources.
Canvas will reference the questions you choose as each student takes the quiz. These questions will stay in sequential order and stay in order each time the quiz is taken or previewed. If you want to randomize quiz questions, you can add them to a question group.
Note: When you Find Questions in a question bank, changes made to questions in the question bank will not update in the quiz. Changes will update in the quiz only if the questions are linked to a question bank.
