Once you publish a quiz and make it available to your students, you can make changes to the quiz. However, students who have already opened or completed the quiz will not see any changes you make, which may affect their grades. If necessary, you can use quiz regrade to edit certain types of quizzes.
Click the Quizzes link.
Open the quiz by clicking the Pencil icon.
If one of your students has opened or has already taken the quiz, you will see a warning notification at the top of the quiz. If you change the quiz contents, you will need to either grant them permission to retake the quiz, or you can regrade the quiz to compensate for any changes.
Edit any quiz
After a quiz has been published, you can also grant extra time and attempts to all students or individual students.
To edit quiz questions, click the Questions tab.
To notify the students in your course that the quiz has changed, select the Notify users this quiz has changed check box. 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.
Click the Save button to save your changes.
You can also Preview the Quiz again [1]. When you are ready, click the Save It Now button [2].
