It's well written and detailed. As long as you listen carefully and finish your math homework carefully, you can keep up. At first, I heard the scores clearly. 10 class is also very good, and the children in front are also very energetic. If many can't, the teacher will pick out a few lessons to review. The effect is quite good. Very kind, the key is that the steps and logic of solving the problem are also well analyzed. I'm studying there now and I think it's not bad. The key is to get used to the teacher's speech. Follow the teacher in class, listen carefully, take notes and think positively, so as to learn well, otherwise the teacher is no better.
