As a former Harvard admissions interviewer and a Harvard graduate, people are always telling me their GMAT scores and asking "if I think they'll get in."
In my view, one needs a GMAT score between 680- --> 720 to be considered competitive at the "Top Ten" and Ivy League schools, and anything over 720 will put you in a completely different (i.e. excellent) ballpark and that is what you should shoot for in terms of really making a great impression with the ad com.
I have also found that in working with my own MBA clients over the years, that those who actually take an organized 6-8 week class do slightly better than those who study alone with a book or online. I have also found that scores tend to weigh just a little bit more for international candidates.
The overall goal is to make you an extremely strong candidate and not give them a reason to say no. A 720+ does just that.
