Many people ask me, how many hours is it appropriate to make up lessons at a time? Three hours. God, I don't think I can talk for so long. Let me talk about me and a child I am taking now. When the two of them sit down, I will ask him what he studied recently (or this week), whether he took the exam or not, and how many points he got. If he had a test paper, he would read it. Then he took out the counseling book he bought and began to do the problem. Make an answer to a question. If it's right, skip. If it's wrong, take a look at it for him. I watched him do the problem and occasionally compared the speed of solving it with him. Take a rest after studying for an hour, chat and watch mobile video or something. Then continue to brush the questions. Finally, leave 20-30 minutes to play. Yes, you are right. He brought me the glory of all kings. Finally, if you think it is difficult to be a tutor, and you don't remember the formula, which makes students feel insecure, then you think you should buy a tutorial book and start reviewing your knowledge first. Opportunities are reserved for those who are prepared!
