2, Zhejiang University "Senior High School Mathematics Competition Training Course" (Try 2), Li Mingde.

3. Detailed explanation of the previous real questions of the National Senior High School Mathematics League published by Ming Kai Publishing House, edited by Qi Mingxin.

The Road to Gold Medal published by Shaanxi Normal University has been revised, but the cover can't be found. However, this series of physics articles was written by Zhang Datong, a master of physics gold medal.

5. Zhou Zemin, the trump card of the competition published by Shaanxi Normal University.

6. The series of "Olympic Classics" edited by Wenxuan, Leng and Hunan Mathematical Society was published by Hunan Normal University.

7. Towards IMO was published by East China Normal University and compiled by Jia Lian Group of China National Training Team.

Increase in the order of the above difficulties.

If you decide to buy it, you can show me the cover. I have used all these before, and the last two books are basically new, so I didn't learn much, and the competition for books was basically over.

Every book is a classic. It's just that I didn't learn well by my own disappointment, but I don't feel like a book.

You can also find a book about Chen Dingchang, the headmaster of Huanggang Middle School. He teaches mathematics and is a master. The books written should be no different.

Generally speaking, Shen Wenxuan's math contest books are good, and East China Normal University's math physics contest books are excellent.

Exams also depend on improvisation. Basically, if you take five sets of pre-school seriously, you can get the first prize in the country and participate in the exemption of the top 20 universities in the country. If you pass the exemption test, you don't need the college entrance examination. Meanwhile, you can choose to join the provincial training team to promote CMO.

If you learn the latter two sets well, you can enter the national training team through CMO, then participate in the winter camp, and maybe even participate in IMO.

As for joining the international training team, don't use the textbooks on the market. After learning these seven books, you must rely on your own cultivation. It can be said that no one in China taught you to join the national training team. Teachers can only play a guiding role, because students have surpassed teachers.

China has always been very good at IMO, and winning an award at IMO, at least when he was young, was a great honor. Such people are not too far away from real mathematical research and great mathematicians. Of course, the academic environment in China is not good the day after tomorrow. Many excellent IMO winners in China finally disappeared because there are things that tempt them more in reality. Once their hearts are floating, learning is a very difficult thing.
