The highest GMAT score possible is 800. It may seem impossible to attain a perfect score of 800 in the GMAT, but with pure hard effort, devotion, and the correct study plan, it is doable. Even elite B-schools demand candidates to score 720 or above, thus a perfect 800 is not required to get into a top Business programme. If you receive a good grade, you'll be able to apply to a top business programme.
