The Academic Technology Team and D2L support have discovered a product defect regarding Quizzes and Special Access in My Courses. Below, we have outlined the defect and provided a workaround until a permanent fix is released. 

Defect: 

For Instructors: When using the special access tool to give a user additional attempts, the setup from the instructor side works as intended. 

For Students: When trying to access the quiz with special access from the content area, the students won't see any changes in the default settings.

Workaround:

The Academic Technology Team has added a link to the Quizzes tool under the Tools section of the course Nav Bar. As needed, instructors should notify students that they can use this link to access their quizzes but won't be able to make any edits. When students access quizzes from the Quizzes page, the Special Access displays as intended, and the students are able to take any additional attempts.
