School’s back in session and for U.S. business schools, many eager to advertise their worldliness, that means welcoming droves of students who don’t call America home. Stanford Graduate School of Business boasts a recent class that is 42 percent foreign.  Harvard Business School’s Class of 2014 was 34 percent international. More than one out of three students at the University of Chicago Booth School of Business now calls somewhere else home.

So which country outside the United States is home to students most interested in studying there? The best measure may be the Graduate Management Admission Test (GMAT), administered by the Graduate Management Admission Council (GMAC), which is typically required by M.B.A. programs in the United States.

In China, where the number of college and universities has doubled in the last decade, the number of GMAT exams taken has boomed from 8,779 in 2000 to 62,740 in 2015. And while China and India, where 29,055 tests were taken in 2015, now represent the vast majority of GMAT tests taken aboard, the rate of increase in test takers has grown far faster in other countries, according new numbers released by GMAC to TIME.

The number of tests taken in Saudi Arabia has gone up 952 percent from 252 in 2000 to 2,400 in 2015. The number of tests taken in Vietnam has increased 921 percent from 163 in 2000 to 1,501 in 2015. In Kuwait, the number has jumped from 95 to 647 during that period. While in Nepal, 506 tests were taken in 2015 compared to 75 tests in 2000.

U.S. test-takers now make up a little more than a third of all test-takers when they once represented a majority. The increased international competition hasn’t shown American students in the best light. Students from Asia-Pacific countries now greatly outperform U.S. students on the quantitative section of the exam, the Wall Street Journal reports.
