Applicants who submit a GMAT score which does not meet the minimum requirement of 600 for the old version and 605 for the GMAT Focus version set by RSM will not be considered for admission. You can take the test again, but the new score must be submitted by the application deadline, or before the programme has reached maximum capacity (whichever occurs first). If your score is too low and you do not plan to take a new test, you need not apply. 

RSM will only consider the highest score obtained. A previous lower score will not have a negative effect on your application.
