You can create a quiz using a Question Group linked to a Question Bank.
When you link a Question Bank to a Question Group, 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.
Curve will reference your chosen bank of questions as each student takes the quiz. Each student will get a random number of questions pulled from the bank. For instance, if you want to use questions from the English Department and they have 7 questions in their Question Bank, but you only want the Question Group to display 2 questions, Curve will randomly pull 2 of the 7 questions as each student takes the quiz.
If you need your questions to appear in a specific order, you should add individual questions or find questions instead of creating a question group.
Note: When using question banks, be sure to make changes within the Question Bank before linking the quiz to the question bank. Although you can make changes to the question bank after a quiz is published, students who have already opened or completed the quiz will not see any of the changes, which may affect their grades. Students who begin their quiz after the changes are made will see your updates.
Note: Questions that are linked to a Question Bank cannot be regraded since they may be used in more than one question bank.
