You may take the GMAT® exam once every 31 calendar days and no more than five (5) times in a rolling 12-month period. If you score an 800 on the exam, you will be prohibited from testing for five (5) years from your exam date.

The retest policy applies
        even if your score from a test administration within that time period is canceled by you, Pearson VUE and/or GMAC® (see Canceling Your Scores).
