When it comes to compulsory education, many people think that the state provides free teaching environment and educational places for children. However, many people are not clear about the characteristics of compulsory education. Recently, we can see the compulsory education policy put forward by relevant personnel. They said that schools should not be divided into key classes. This resolution has been endorsed by many netizens. Because if students are divided into three, six, nine grades, the students at the higher level will work harder, and the students at the lower level will give up on themselves. They usually classify themselves. So if we don't divide the key classes, then they won't have such an idea.

In life, we can often see that students in key classes work hard and teachers are particularly strict with them. Teachers are willing to spend energy and time on these students because they think they have potential. As for the students in the ordinary class, the teacher thinks that no matter how hard they work, the children will not perform well, so they are particularly relaxed. If students are not divided into ordinary classes and key classes, there will be good students and poor students in one class, and teachers will teach them equally, and students in different classes will not be treated equally, nor will they have some bad psychological tendencies.

If there are some good students in the class, then they will take the initiative to study. For some people with poor self-control, they can join the learning atmosphere automatically under the guidance of these good students. This is also beneficial to class management and students' physical and mental health.

For students in the lower age stage, it is not necessary to divide them into key classes and ordinary classes. Because children at this stage are particularly malleable, if they are divided into good and bad as soon as possible, they will lose confidence in themselves. Then they will not have much motivation when they study in the future.
