When is Zhao Zhongxiao in the exam?

Junior high school students usually take the exam in June. Primary school graduates who attend private or children's schools or public boarding junior high schools with surplus degrees will receive the final admission result, and the original allocation result of public junior high schools will be automatically cancelled (it is forbidden to change the status of public and private schools). The way to fill in and enroll volunteers in public junior high schools is that every primary school graduate must fill in a volunteer and go to one or several secondary schools corresponding to his primary school for further study. If the number of volunteers reported by a primary school in a middle school is less than or equal to the enrollment index of the primary school, he will be automatically admitted to the middle school; If the number of volunteers in a middle school is greater than the index number of the middle school in the primary school, microcomputer allocation will be adopted for admission. After volunteering, no one can change.
