Are you Hunan Education Edition or People's Education Edition? I am from Xiangtan, our Hunan Education Edition. If you are a tutor, I think the new classroom relay is very good, and one plus one textbook is ok. For middle and lower students, top students will learn cases. People's education edition should also have it. If you do the problem, it is ok to simulate the five-year senior high school entrance examination for three years. I also bought Haidian's test paper and made it myself. I won the championship easily, and the amount of questions was a bit large.
