All that matters in the high stakes testing at the end of high school known as Gaokao. That's it. Get a high score on that and you're made in the shade for life pretty much. You can sleep through three years of high school there (most students do, especially the boys), not go homework or piss off your tests, and it won't matter.
See, being with your friends is more important in a Chinese school than actual academic achievement. So they piss off years one and two and step year three just prepping for Gaokao. Higher the score = better acceptance chance at a "good" school. It would be the equivalent of this: Good score = Ivy League/Johns Hopkins. Bad score = going to a diploma mill.
Once in college getting a BA, it is nearly impossible to flunk out. The only real was to get expelled is by a rule violation (not academic dishonesty because that rampant in all levels of education in China), such as not being in your dorm room after lights out (which is normally a room with six to eight people, no amenities except a bunk bed with a thin mattress and a wooden board as a box spring in which they lock you into the building after lights out).
As one former student told me; "getting into an American university is easy, but it is hard to stay. Chinese universities are nearly impossible to get into and completely impossible to fail out."
Just because you have a BA in China doesn't mean you know shit or were even educated at all.
