Your instructor may have set availability dates that determine when you can submit your quiz. If you are not within the availability dates, the quiz will display as locked and you will not be able to submit your quiz.

Begin by clearing your browser’s cache and cookies.

If clearing your cache and cookies doesn't resolve the problem, something in your browser may be blocking your access to submit your quiz. To verify this, try using Chrome’s incognito or Firefox Private mode.

If you cannot submit your quiz using an incognito or private browser, try using a different browser. Canvas generally recommends using Chrome or Firefox.

If enabled by your instructor, your quiz might require the use of the Respondus Lockdown Browser to start a quiz.

Note: For additional help, view the Lockdown Browser resources. 

For assistance on other proctoring services you may need to reach out to your instructor or institution for further help.
