Do more questions and let him talk about your mistakes. What kind of teacher are you if you don't go home to class? Just attend classes and go to training classes on weekends.

If you can accept what the teacher said, don't change it. If there is a problem, let your parents talk about it, and the effect will be better. If what he says is the same as gobbledygook, the tutor who only knows how to write questions and comments is a waste! ! !
