WHARTON的回复
Wharton views the GMAT scores of all nationalities equally. And an extremely high score doesn't really confer any advantage over one that is merely 'very strong'.
Think of it as an Olympic hurdles race - the object is to clear all hurdles cleanly, but only just. Spending time and effort training to clear the hurdles by a lot is wasted, and actually slows you down - and the race is won by speed, not height. Same thing with the GMAT - you are wasting your time retaking with a 720.
For applicants who come from educational systems where admissions are based heavily on entrance exam scores (and who achieved success under that system), there is a tendency for them to assume that admissions to Wharton works on a similar basis. When they network with people who come from the same education system, such perceptions can get reinforced, and it is easy to see how an 'arms race' of increasing GMAT scores can develop amongst such applicants, even if it has very little relevance to how adcom actually make admissions decisions.
