Certification passing

That's normal. It usually takes up to 24 hours to get the result by mail.

Final results will be posted to your AWS Certification Account within five business days after the close of the exam.

Based on my experience, I was able to receive the result email 6 to 8 hours after completing the exam.

If you login to your AWS Certification account and keep an eye on it, you can sometimes find that your result is posted there a little bit sooner than waiting for the email is sent out.
