Chinese ATP
I'm the proud holder of a Chinese ATP (sic!).
Although I now hold a bit more "gouge" on study materials for the Chinese ATP, I agree that the best thing to study are the FAA ATP testing material from Gleim, King, and other sources. I had about 10 questions on my ATP exam that were obviously Chinese generated questions. One had to do with "male arousal" .... There were two questions on my exam that were written in Chinese .... There were two questions to which there was no correct answer. I queried the proctors about the available answers and they agreed that none of the answers were correct but that I should "guess and hope".
Bottom line -- study the FAA questions. That's about the best you can do! Good luck!
