What kind of GRE score would you need to become competitive at top-tier business schools?

Short Answer: Bschools don't do check the concordance table. Long Answer: There are few things in this GMAT versus GRE debate: 1) The percentiles don't match apples to apples. This is something people don't realize but the average GMAT test-taker is considered more "mature" than the average college-going GRE test-taker. So a 90th percentile on GRE may actually match to a 80th percentile on the GMAT. Is there a *real* concordance? We really won't know :) 2) For long ETS (the current administrator of GRE and the past administrator of GRE) tried peddling GMAT to bschools. So in some sense it is a victim of its own plans. So it is deeply embedded in bschool psyche. 3) 340 is an ugly number - 800 is not. Relatively speaking, ofcourse :) So people still struggle to understand a "good" GRE score - more so after the new GRE was launched in 2011. While in GRE it is never a combined score but individual Q & V scores that add up. Doesn't make sense to people so they don't like to touch it. Especially potential employers. 4) As a corollary to the above point, schools find it difficult to compare students applying with GMAT scores (a vast majority) & students applying with a GRE score (a minority). So that can also be a disadvantage. This gets exacerbated when you take many Bschool rankings, which rely on the "average" GMAT scores. Arun
