According the table above, If the difference of 64 points is true it is at least possible that the average of chinese students in H/S/W ( GMAT average about710) is about 770. Although above 750 are ourliers, H/S/W are outliers too.
切, 我知道W, H ,S去年从中国大陆收了很多G很一般的人, 750以上的在大陆的被录取的在这些学校倒是凤毛麟角, 某些排名很靠后的但是又要自称牛校的PROGRAM倒是对G要求颇高
