I don't think so. The class representative is the teacher's assistant. Many of the homework assigned by the teacher is said in class, or given to the class representative, who writes it on the blackboard or sends it to the WeChat group. The class representative gave the teacher a lot of help. Teachers should not be disgusted and criticized, but should be grateful. It is a very worry-free and lucky thing for a teacher to have a capable and responsible teaching assistant or class representative.
