dxj

for your reference

one friend  gmat 700, INSEAD

second, 670, Carnegie Mellon

third 740, thunderbird with full fellowship

forth, 750, Michgan Ross

do you think there is a linear relationship between the score and school ranking?  No

I think most of it depends on the candidates quality and potential.  Prepare well your ESSAYs.
