What is a good GMAT score for premierB-Schools? (2)

The 2018 average GMAT scores for students at Harvard and Booth were 731 and 730 respectively.
Remember, those are average GMAT scores, which means that individual scores at each of those schools can be either above or below those numbers. 

After you calculate your GMAT score and your GMAT score is, say, 740, then it would be above-average for every business school in the world.  For the other premiere business schools, the average GMAT scores are between 715 and 733.  If you score above 710, your score is in the territory of the elite schools, and if you score anywhere above 750, your GMAT score is stratospherically high.

If your GMAT score is currently in the low 600s and you would like to move to the high 600s or even low 700s, it is critical that you start practicing the right resources now. GMAT classes in Chennai will help you achieve your target score if you are wise in choosing the right one.
