Teaching assistants interview about 20 students every day and give feedback to the parents of students above 15. The class time is particularly short, and the teaching assistant can only pay attention to quantity rather than quality. It is particularly annoying to often come to the interview when students are doing their homework and interrupt the thinking of solving problems. Call your parents if you don't know the situation. So what if the teaching assistant is a prestigious school? It's best not to do anything in the classroom for a day.
