Hi Thalita,
Good day! Thank you for posting to Microsoft Community.
I do understand your query here but, as your query is related to Microsoft exam and since Microsoft has specific support channel resource for certain different support scope and attributes, we belong to Microsoft Forum Community mainly focused on Microsoft 365 Exchange online only. Therefore, we provide some limited knowledge about some aspects of certificate and exam related scenarios. For your query, we have a dedicated team with special expertise in Training, exam and certificate related queries, so would you mind connecting and place your query on our dedicated support team via ticketing. We believe they will give you accurate and efficient solution for your concern.
