I am the winner of the first prize in Shanghai this year. 86.5 points. In my opinion, it is best not to read some particularly advanced chemistry college textbooks, so those Olympic Games will not be tested. More than half of the Olympic Games are actually testing the structure. I suggest you read Organic Chemistry edited by Gao Hongbin and Inorganic Chemistry edited by Wu Guoqing. Structural chemistry edited by Zhou Gongdu. Do some college exercises while watching. After reading it, and you have your own ideas, then do the topic of the Olympic Games. I suggest you buy "Sprint High School Chemistry Competition", which has a comprehensive topic.

It is best to look at the atomic structure and molecular structure first, and it is best to explain the problem from the perspective of atomic structure and molecular structure. A master of chemistry must be a well-structured person.
