Best answer by JeffHall
* If a candidate fails an exam on the first attempt, he or she is allowed two additional attempts.
* There is a seven-day waiting period between attempts.
* After three attempts, you will be unable to take the exam for 60 days, after which you can e-mail firstname.lastname@example.org and request that your attempts are reset.
After resetting your attempts, you can start the process over, if needed.
Hope this helps!
