Hi siddharthm20,
Most Business Schools generally do not care if you take the GMAT more than once - so submitting more than one Official Score to a School will probably not be an issue. Many Programs have stated that they consider the higher/highest Score submitted - and even if you do not improve with a second (or latter) attempt, you can always 'cancel' that result so nobody sees it besides you. That all having been said, if you'd like to know how a particular School/Program handles this issue, then you can research that Program (and you might consider reaching out to the School's Admissions Department to ask).
1) How did you score on your 1st attempt?
2) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
