Not Asian-Americans, but Asians from Asia:
They’re far outpacing Americans, particularly on the quantitative section of the test. Many B-school admissions officers say that a score on the quantitative section is the best predictor of success in an MBA program.
One result of these disparities is that Americans’ percentile rankings have dropped, even though their raw scores have remained constant in recent years. With Asia-Pacific students applying to and attending American business schools in large numbers, some schools complained to the Graduate Management Admission Council (GMAC), which administers the GMAT. As the WSJ put it, schools “don’t want to become factories for high-scoring test-takers from abroad.”
