How the MS-721 exam is scored
Microsoft scores every certification exam on a scale of 1 to 1000, and you need 700 to pass. This is a scaled score, not a percentage: the number of questions you must answer correctly shifts slightly with each exam form so that a 700 always represents the same level of ability. There is no penalty for guessing, so answer every question even if you are unsure. Unanswered questions are always marked wrong.
Your score report groups results by the skill areas below. A fail in one area with strong scores elsewhere still fails the exam overall, so use your report to target the weakest area first before rebooking.
