Test takers may register for the GMAT either online at or by calling one of the test centers.  To schedule an exam, an appointment must be made at one of the designated test centers. The GMAT may not be taken more than once within 16 days, even if the scores are canceled. Official GMAT exam study materials are available on the online store and through third-party vendors. The cost of the exam is $250. All applicants are required to present valid ID when taking the test.  Upon completion of the test, test takers have the option of canceling or reporting their scores. As of July 2014, test takers were allowed to view their score before making this decision.
