The average GMAT score worldwide is 570. There is no “acceptable” or “minimum” score. What score you should obtain depends on which school you are going to apply to. Generally, the higher the school ranks, the higher score you must obtain. For the top 50 programs, the averaged GMAT score is 660. Things could be different if you are not so particular about applying to the ranked MBA programs. The GMAT could be one of the most important factors for admission. If you have a score that is much higher than the average GMAT score indicated by the university, your chances of admission are really good as long as you fulfill the basic requirements.
