One of my roommates in college was from China.
We had a lot of foreign exchange students from there, many of whom I found out in labs had very poor writing skills.
I asked my roommate how so many Chinese students found their way to this college and why the writing seemed so bad.
He explained to me there was literally a whole industry in China dedicated to faking the scores and documents required to get Chinese kids into good schools in the US.
This included all sorts of College apps, essays, and probably some of the tests like the ACT.
He said wealthy families in China valued education as a status symbol and would pay top dollar to get their kid into Harvard or so on to make them look good, himself included
