As tens of thousands of Chinese students prepare to study in the U.S., they might reflect on the experience of some of those who went before them. According to an estimate by a U.S. education company, some 8,000 Chinese students were expelled from American universities last year alone – and the main reasons were poor grades and cheating.

Phony diploma mills that use “slick websites” and claim to be “nationally accredited” to lure honest students looking to improve themselves through education only offer certificates costing hundreds of dollars that “are not worth the paper they are printed on”, according to a report from ABC Action News WFTS in Florida.

An unusually high number of students at Stanford University are suspected of cheating during the most recent term, putting faculty members and administrators of the prestigious institution on alert. University spokeswoman says that in the 2013-2014 academic year, 83 students violated the honor code. In the most recent term, the newspaper reported that one instructor believes that 20 percent of students in a large introductory course may have cheated.

It’s raining As in America’s higher education system, and not necessarily because students are particularly smart. In fact, many of them probably don’t deserve the high marks they’re getting. They have grade inflation to thank. That inflation is rapidly spreading to higher education institutions across the country. Despite stagnant academic performance, more students than ever before receive higher grades than they should.

An eight-month investigation by former federal prosecutor Kenneth L. Wainstein has found that more than 3100 University of North Carolina at Chapel Hill students – almost half of them athletes — were given credit for "irregular" (read: nonexistent) classes over an 18-year period from 1993-2011 as part of a organized scheme that allowed many to remain sports-eligible.

Thirty-five former school officials have been implicated in a test cheating scandal, and have been given a deadline to surrender to authorities in the state of Georgia. The accused in the city of Atlanta face counts of racketeering, making false statements and conspiring to improve test scores to win cash bonuses.

Although Chinese students have been going to America to study for decades, their numbers have grown dramatically in the past few years. Many of them have only a basic knowledge of foreign universities and difficulty making sense of complicated applications. As a result, a huge industry of education agents has arisen in the country to help guide them — and, in some cases, to do whatever it takes to ensure that they are accepted.

Easy A's may be even easier to score these days, with the growing popularity of online courses. Technologically advanced students are finding ways to cheat that let them ace online courses with minimal effort, in ways that are difficult to detect.
