Although I am from Nanjing, I just finished taking the senior high school entrance examination this year, so I can give you some suggestions. It stands to reason that there are all big bookstores, or it may be that the school orders the national real questions in a unified way. At that time, we wrote 38 sets of Tian Li, and it is said that 45 sets of papers are almost good, but I think the papers from Beijing, Jiangsu, Shanghai, Huanggang and Shandong are better. Mathematics is the mainstay. The last two questions can be written without doing it yourself, because this kind of big question is really an exam. Try to listen to the kind of fate, so the foundation is the most important, just like the last math problem in my senior high school entrance examination this year, 1 12, I can't do it at all.
