Once again, I’m not sure why you are focusing on Chinese speakers. 15X as many AP tests are taken in Spanish. Your post is really coming across as xenophobic, aside from being totally without merit.
Again, it’s only 10k tests. One cannot draw inference based upon a relatively small sample. Plus, relatively few high schools offer Chinese as a foreign language.
REALLY?!?! You did not just say that.
Nobody, other then you, has said that there is any criteria being applied.
