I am a Chinese, this website received some attention in Chinese circle because of this article. So I came here trying to share what I know and feel with you. However, just before starting, I found the recent 2 replies in front of me already expressed most of what I am going to say.
1) Sharing test questions is indeed unfair to any other test takers who do not have such information including many Chinese. And never say or think that people from a certain country, region, ethnic or religion are all blablabla. It's never true but only immature.
2) I don't believe the high score is so easy to get as some people think even with so called "jj". Many test-takers in China fail for several times before they get a pleasing score. The GMAC and business school can't be so stupid. The major reason that some people win, I believe, is they spent much more time and energy than you imagine.
3) GMAT is just one criterion that business schools use to select candidates. And even a well-known MBA degree is just one tool to help you to succeed. If such things bother you a lot, you can not survive in a fierce and dangerous real society; no mention the elites' circle.
4) Another reason that Chinese get so high scores is that they have much less other material or background to distinguish them when comparing with native candidates. And they just compete with themselves, at least no more than Asian. To be honest, as English-speaking people, if you are so worried about the GMAT, GRE, LSET and CFA etc. how do you think a Chinese would feel on them? These exams from the U.S. never think they need to consider the candidates' English ability but just test other ability or knowledge in their own language. So the world never offers absolute and forever justice. As a feeble, the only thing could do is to fight for what you want or give up. Right now, more generally speaking, when comparing the Chinese with Westerners, they may have more chance, but they definitely face more difficulties.
As a Chinese, I sincerely invite you to come to China and meet some Chinese, or at least, read and listen more about China. It is neither a country of hero nor evil. It's a country with one fifth of the world population, the same size as the U.S., the same GDP as Japan and what's more important, a country with thousands of years of history once hit its summit in Tang Dynasty.
P.S. Since China has a totally different (and confusing) political system from the U.S., please never put Chinese government and its people together.
