Hi partner,
Yes, we have to pay again for a retake.
If I do not pass, what can I do?
Prioritize the skills that you should practice by focusing on the content areas where your exam performance was the weakest and in the content areas that have the highest percentage of questions. Additionally, you may want to review the resources provided on the exam details page, and our Study Groups, which can be found at the bottom of the individual exam details page.
When you are ready to retake the exam, schedule an appointment as you normally would. Note that you must pay for each exam you retake and follow Microsoft’s retake policy.
There is currently no document mentioning the maximum time limit for retakes, so you can rest assured that there is no maximum limit.
