You can grant access to an individual student, several students, or the entire class to have extra attempts on a quiz. If your quiz is locked, you can also manually unlock the quiz for a student, even if the student has not yet taken the quiz.
You can add extra attempts through accessing student quiz results or moderating the quiz.
Accessing Student Quiz Results is a quick way to allow an extra attempt for an individual student.
Moderating the quiz lets you allow extra attempts for individual students as well as multiple students at once. This option also allows you to grant extra attempts for students who have not yet taken the quiz. For timed quizzes, you can grant extra time for an attempt. If your quiz options allow students to view results only once after each attempt, you can also let students view quiz results one more time.
You can also use these options to remove attempts as well. For instance, if you need to remove a student attempt, you can decrease the attempts accordingly.
In Course Navigation, click the Quizzes link.
