Fraud in China is not uncommon. After all, this is THE country for knock-offs & fake anything-under-the-sun.
But after going through the process of college applications (2nd time around now in progress) and the laborious efforts that are needed to write those essays & fill in those application forms & meet those deadlines, it angers me that so many Chinese students are getting in through unethical ways & means.
I have heard of how some of the local SAT "schools" hothouse the students - it's not about learning vocabulary, but it's about statistics & tactics. Eg. if it's question 58 on the reading test, you have a higher chance of a correct answer if you mark "B" on the answer sheet. It's not as ludicrous as it sounds - the Chinese have the gumption of collecting years & years worth of SAT questions/answers, doing statistical analyses on it then come up with probabilities which are used to "teach" these students.
I hope that the colleges in the US wake up to this aspect of admitting students from China.
