Features: The subject Olympiad for primary and secondary schools (abbreviated as "subject Olympiad") is one of the most extensive, widely participated, and influential subject competitions for primary and secondary school students in China. The subject Olympiad draws inspiration from and extends the concept of the International Mathematical Olympiad (IMO), the International Physics Olympiad (IPHO), the International Chemistry Olympiad (ICHO), and other internationally influential subject competitions for secondary school students, which attract millions of young students every year. The reason for such widespread attention lies in the Olympiad's strong innovation, flexibility, comprehensiveness, and emphasis on cultivating students' exploration skills and inspiring their innovative awareness. These are precisely the core elements of quality education, which are also essential for future development.
Based on years of in-depth research on this activity both domestically and internationally, as well as a vast number of outstanding books in this category, the Editorial Board of the Subject Olympiad for Primary and Secondary Schools has invited outstanding educators dedicated to this field from all over the country to compile and publish a series of Olympiad books titled Gold Medal Olympiad and Gold Medal School, covering seven subjects—mathematics, Chinese, English, physics, chemistry, biology, and information science—with over 200 varieties. In terms of the variety, quantity, and quality of our Olympiad books, we are considered the most influential in our field both domestically and internationally, and are highly regarded by primary and secondary school teachers and students.
The purpose and characteristics of the Gold Medal Olympiad and Gold Medal School series are as follows:
1. High: Derived from the curriculum but exceeding it. Derived from the curriculum means referencing the new [curriculum standards] issued by the Ministry of Education; exceeding it means closely aligning with the competition syllabi at all levels, ensuring comprehensive alignment in content, question types, and skill requirements, thereby fostering interest, developing intelligence, and enhancing abilities.
2. Accurate: Scientifically precise and logically structured. Each book is designed according to the characteristics of the subject, scientifically organized, and follows a step-by-step approach, providing in-depth yet accessible analysis and detailed problem-solving methods.
3. Innovative: The questions are novel, unique, and engaging. They collect the essence of recent Olympiad, middle school, and high school exam questions from both China and abroad, representing the highest level of current Olympiad standards and reflecting new concepts in curriculum reform, as well as new ideas, methods, and trends in competition question-setting.
4. Refined: Selected examples are challenging yet not obscure, flexible, and achievable. The focus is on learning through examples, generalizing from specific cases, and encouraging multiple solutions, variations, and extensions of problems. Emphasis is placed on training thinking skills rather than rote memorization, making learning an enjoyable hobby.
5. Renowned: A gathering of distinguished experts and a collection of elite competitions. The Editorial Board of the Subject Olympiad for Primary and Secondary Schools has invited renowned professors from prestigious universities, special-grade teachers, senior teachers, subject leaders, and famous Olympiad gold medal coaches to contribute to the series.
