The job of subject 3 security officer seems simple, but it is really not easy to do, because the students in the exam are all novices and the operation is easy to make mistakes. Examination cars shuttle between cars, and sometimes a mistake can lead to great disaster.

Then someone will ask the security officer how much commission he can get through a student. This is not right. Students pass subject three, the coach can get a commission, and the security officer only works. If the security officer can get the commission from the students, the pass rate of subject three will not be so low. After all, many students failed the exam because the security officer stepped on the brakes. Stepping on the brakes does not mean that there is immediate danger, but the safety officer is unwilling to take higher risks, so in some cases, the safety officer is very active in stepping on the brakes.
