He is an assistant to the math teacher and one of the good students in the class (not necessarily).

The supervisor sends and receives math homework, marks papers and grades, and helps teachers do things.

I am a representative of math class, and the only thing in our class is the most unforgettable thing in my three years in junior high school.

It is because I am a representative of math class that my math scores have steadily improved.

Thanks for this position!

The representative of math class is the person who has the closest relationship with the math teacher among the students, and has more opportunities to communicate and discuss with the teacher. He is under the jurisdiction of several group leaders. When the teacher is absent or studying by himself, he also acts as a temporary inspector or lecturer.
