Once you publish a quiz and make it available to your students, you can make changes to the quiz. Original quiz data is retained as part of any existing student submissions. However, students who have already opened or completed the quiz will not see any changes you make, which may affect their grades. These types of changes include adding new questions or deleting questions from the original quiz.
Additionally, if you change only the point value of the quiz, the student's submitted quiz will show the updated point value, but the current grade won't change in the Gradebook.
If you only need to make changes to existing quiz questions, after editing the quiz you can use quiz regrade to edit certain types of quizzes, or you can add fudge points to individual student quiz scores using SpeedGrader. You can also moderate the quiz to give additional attempts.
In Course Navigation, click the Quizzes link.
Locate the quiz you want to edit and click the Settings icon . Click the Edit link .
To edit quiz settings, click the Details tab . To edit quiz questions, click the Questions tab .
Make the required edits to your quiz.
Once you have edited the quiz, you can notify the students in your course that the quiz has changed by selecting the Notify users this quiz has changed check box. The notification will be sent to any students who have enabled the Course Content option in their notification preferences, including students who have already completed the quiz.
Note that students will always receive a notification if you change the due date of the quiz regardless of whether you select this check box.
