In inspira, after I click on "Browse Catalog" in "My Learning", I see the message "You do not have access to Catalog items. Please contact your System Administrator." Who should I contact?

This message means that you have not requested for access to the examination catalog items. Go to My Learning, then click Request for Learning, then select LPE as the Learning Type. The guide "How to create an account in inspira (external applicant) posted here covers how to request for such access. Please try the steps outlined in the guide.
