This app made me pass the exam at the first attempt! I strongly recommend it.
The questions and pictures are the same as the actual English version of the Chinese drivers license test. I just noticed 2 or 3 differences in the translation.
Overall, about 80% of the actual test questions are in the app.
Just train with the app until you score 95-97 then you are almost sure to pass.
Thanks a lot!
