The app should be your first go to if you plan to get a drivers license in China. China has gas vehicles and countless battery powered vehicles. ***IF your vehicle does not have pedals like a bicycle, you need a Chinese drivers license***. I am of the opinion that the rules of the road are near similar in China and the states. HOWEVER... Chinas interpretation of English - on their exam - is enough to flunk the most proficient English speakers. I drilled these bamboozling questions for a week, and I can pass the practice tests, but barely. ...Also, China requires you to retake the test if you accumulate 12 points in a year cycle.
If you want to challenge yourself with the mundane, this is also an app for you. Thanks BeeBusy. I am not a paid endorser.
