I passed the test on April 12. The certificate does not come out yet.

Hello JeongCheol,

Congratulations on the passed exam.

Here is our FAQ link. 

"I am able to log into my CertTracker account. However, I do not see my exams or
credentials. Where did they go?"

Please allow 5 business days for exam data to appear in CertTracker. You will receive an email from Dell
Technologies Education, subject: Dell Technologies Education Activity Result once your results have
transferred over.
If you log into CertTracker after 5 business days and are not able to see the Exams or Credentials tabs
then you MUST update/confirm your demographic information by following the below steps.
               From the top menu bar Select Demographics
               Update information (i.e. relation to Dell Technologies, email address, phone number)
               Scroll to the bottom of the page and click Update/Confirm
Once you update/verify your demographic information you will be able to see
the Exams and Credentials tabs with your history listed.
