If no exam appears
Your Exams lists exams explicitly assigned to your client account. An empty list means no available account assignment is shown. A recruitment invitation may instead provide a private link for one attempt.

Check the invitation and sign in to the account named for the assignment. If it is still missing, ask the person who arranged the exam to check your access. Creating another account or matching an email address does not claim an earlier assignment.
After submission
A receipt confirms that the answers were stored. It does not itself give a score or pass/fail result. Results appear only after release, and the information available depends on that release.
If access is no longer available
An exam can become unavailable after its deadline or when access is withdrawn. A private invitation is specific to its attempt. Do not forward the link or try to use someone else’s account.
Use Contact Us if you cannot reach the person who arranged the exam. Include the exam name and the error you see, without sharing the private link or answers.
