As an international competition, the International Mathematical Olympiad was put forward by international mathematical education experts, which exceeded the level of compulsory education in various countries and was much more difficult than the college entrance examination. According to experts, only 5% of children with extraordinary intelligence are suitable for learning the Olympic Mathematics, and it is rare to reach the top of the international mathematical Olympics all the way.
In recent years, all kinds of extracurricular mathematics classes and training courses in China, which are much higher than the classroom mathematics teaching content, have been named "Olympiad", which makes the cultivation of "Olympiad" gradually break away from the track of selecting Olympiad athletes and highlights the characteristics of universality. Although many well-known mathematicians and mathematics educators have called for vigilance against the deviation of "Olympic Mathematics", the subtle relationship between the results of "Olympic Mathematics" and secondary school enrollment makes the expansion trend of the connotation of "Olympic Mathematics" hard to stop. After-class mathematics training sponsored by various schools and organizations is all wrapped in the cloak of "Olympic Mathematics", which is synonymous with "Olympic Mathematics" because it is divorced from textbooks and emphasizes skills.
