All of the steps in a lesson preceding a quiz need to be finished and marked as complete to progress into the quiz. Some computers with high level firewalls may block the quiz section from popping up, if you believe this has happened try logging onto the eLearning on a different device and see if you have access.
If you do not have access and have successfully completed the preceding steps, it may be an error and needs to be reported to Active Ageing Australia by emailing admin@activeageing.org.au
