Under normal circumstances, some topics of trucks and buses are just some basic topics, the purpose is to let me know the basic common sense, and there are also theoretical books. . . Last week, I just took subject one, and the simulation questions on the internet of public security traffic police are a little more difficult than the test questions. It is suggested to do the simulation questions on the internet of public security traffic police repeatedly. If you can get more than 85 points, you will be fine as soon as you take the exam. . . .
