In fact, any version of the textbook uses the same competition books. I come from Wenzhou. Now I am in Ouhai. When I was in junior high school, I used Meng Jianping and new competition methods to train excellent students. Zhejiang University and East China Normal University have also published some books. Personally, I think there are many mistakes in Zhejiang University, and East China Normal University is more professional. It doesn't matter. If it is scientific, East China Normal University has a good tutorial before the exam. Two days before math, you can buy the inscription of East China Normal University and the Olympic Games course. It is also good to buy the mini series of Orsay, the blue book and the secondary mathematics of Tianjin Normal University in the third grade. If you make a one-year bound book two months before the third grade competition, it will be powerful in an instant. It's a magazine. You can buy it for one year at will, preferably the latest one. The contest has nothing to do with it, just like the contents of the Jiangsu Education Edition and the Zhejiang Science Edition taught by senior high school students are the same, but there is a little difference before and after, as if the answer is late, but I hope who is useful.
