Why does the class teacher charge so much?

first of all, how many semesters have you been in this situation? Generally, the class teacher will announce the accounts to everyone at the end of the term. If it is the first semester, I suggest you wait and see first.

After that, secretly ask other students what they think about this matter. If other students are not satisfied with this matter, some active students in your class will put it forward, so you must keep a low profile. In fact, the head teacher in junior high school has a good word, so don't provoke TA too much (some are unkind, but it's true).

Then, in fact, the best solution is to solve it with the least knowledge, but it is difficult for few people to get it, because it is best not for you to go, so you should see how to find someone to talk to the teacher. If it doesn't work, let everyone know, or report this matter. Think about it and think it over.
