Features: The subject Olympiad for primary and secondary schools (referred to as the 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 and extends from 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 careful research into this activity both domestically and internationally, as well as a large number of outstanding books in this category, the Editorial Department 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:
First: High. Derived from the curriculum but exceeding it. Derived from the curriculum means it is written in accordance with the new [curriculum standards] of the Ministry of Education; exceeding the curriculum means it is closely aligned with the competition syllabi of various levels, ensuring comprehensive alignment in content, question types, and skill requirements, thereby fostering interest, developing intelligence, and enhancing abilities.
Second: Accurate. Scientifically precise and well-structured. Each book is designed according to the characteristics of the subject, scientifically organized, and follows a progressive approach, offering in-depth yet accessible analysis and detailed problem-solving methods.
Third: Innovative. The questions selected are novel, unique, and engaging. They gather 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.
Fourth: Selective. The examples are carefully chosen, challenging yet not obscure, flexible yet achievable. The focus is on generalization and transferability; multi-solution, multi-variable, and multi-question approaches are emphasized; and the training prioritizes thinking skills rather than rote memorization, making learning an interest and hobby.
Fifth: Renowned. The series features contributions from distinguished professors from prestigious universities, elite teachers from key secondary schools, senior teachers, subject leaders, and renowned Olympic medal coaches.
Sixth: Comprehensive. This series includes the following 12 sets, totaling over 200 varieties:
