As far as our school is concerned, a notice is issued around June every year to select a new class tutor. The class teacher is very demanding. First, he has excellent grades. Secondly, he needs to have some experience in student cadres before he can go to the interview. After the interview, he will become a class teacher. After freshmen are admitted, they will help counselors to establish group chats, manage group chats and answer students' doubts. At the same time, after the start of school, poor students will be put into storage, new students will know about the campus, and the monitor and members will be elected. These things will basically be handed over to the class teacher. The planning of later classes and the change of professional academic performance are also places to worry about. Finally, when evaluating scholarships, the class teacher will take the lead to help evaluate and explain the rules. These are the general things that class teachers should do.
