The simulation consists of 30 questions about traffic, each question has 4 alternatives, only one alternative is correct, to pass it is necessary to get at least 21 questions correct.
In the official exam, the time to answer the test is 60 minutes, but the time shown in the simulation is only for you to have control over. If more than 60 minutes passes, you will continue to respond normally.
But remember, in the official test you cannot exceed this time. The questions are random. At the end of the simulation you will be able to see how many questions you got right and how many you got wrong.
