Course arrangement must adhere to the principle of "fairness, justice and openness". Under the supervision of parents and teachers' representatives, classes are arranged in a balanced way by random lottery, and team leaders are allocated in a balanced way to ensure that students receive fair education.
After the first placement, students who report again after September 1 will be randomly arranged by the computer at the designated place and time according to the same procedure and age. The number of executives is balanced, and the number of people will start from less classes. Schools should report the second placement time to the primary education department in advance.
