@AlecTrevelyan Not a problem! After the third exam attempt, you would have to wait 180 days to take the exam again. Then if you fail the fourth attempt, it will revert back to the original wait period (30/90/180 or 90/90/180). For example, if the candidate failed the third attempt at the CISSP, they would wait 180 days for the fourth attempt and if that attempt is failed, the fifth attempt would be 30 days. Important to remember though, you can only take an exam 3 times in one calendar year.
