You can find your submitted exam in Inspera under «Archive».
Normally, you can access your submitted exam immediately after the exam is over. In some situations your submission will not become available (for example if the exam includes a multiple choice test that will be reused).
Notice that access to Inspera requires an active student status at Nord University. You retain access 60 days after you are no longer a student. If you want to have access to your submission after these 60 days, you must download it and save it outside the system.
