How should I reply to the teacher's reply about the postgraduate entrance examination? Urgent online, etc.

Your boy is too impatient. Which tutor do you want to take the exam? You'd better think it over in your mind before the preliminary test results come out. I think that tutor is good. I decided to take the postgraduate exam, but the key is that you should do what you should do, learn professional courses well, keep learning English, and it is best to practice oral English more. Mathematics should not be interrupted. Politics can be put off until half a year after the senior high school entrance examination, but those courses must be paid more attention to. Listen carefully. It's a class anyway. Others may sleep soundly and have a good time, but you'd better be careful, so that you will have a good and high starting point from the beginning. When you really start reviewing, you will find that it helps you a lot. Do your best, don't do one thing twice or more. Believe in your efforts, and you will get good grades. Besides, if you study hard, your tutor will know.
