In case of disconnection, the staff will arrange for students to retake the exam.
If the system does not broadcast the results at the end of the exam, it is obvious that there is something wrong with the system, or the signal may be delayed. Don't unbuckle your seat belt when these situations occur. If the system returns to normal after loosening, the judgment result is unqualified. Once this happens, don't get off the bus, don't panic, and wait for the result calmly in the car.
