"Examination right" is the embodiment and refinement of citizens' right to education, and it is also a basic human right of students. In the final analysis, it belongs to a social public activity in which citizens participate in state affairs through the national competition mechanism. Without the permission of the state, no unit or individual has the right to deprive candidates of their examination rights. Therefore, it is not only a helpless strategy, but also an illegal act to prevent students from taking the exam (even if the right to take the exam is suspended).
