Features: The "Olympic Subject Competitions for Primary and Secondary Schools" series consists of over 200 varieties, including textbook series, introductory textbooks, practice papers, mock exam papers, intensive textbooks, classic problem-solving series, weekly tests, question compilations, and multi-solution series. This series is organized by the Editorial Department of Primary and Secondary School Subject Olympiads and is a research outcome of the Beijing Step-by-Step Quality Education Research Institute. Since its publication by the Olympic Press, it has stood out uniquely and is deeply loved by teachers, parents, and students. After significant revisions, re-editions, or complete rewrites, it has been renamed as "Golden Medal Olympiads" and "Golden Medal Schools," and is now re-published and distributed by Jinghua Publishing House. At this re-publication, sincere gratitude is extended to millions of readers across the country.
The Primary and Secondary School Subject Olympiads (briefly referred to as "Subject Olympiads") are one of China's most extensive, widely participated, and influential subject competition activities for primary and secondary school students. Subject Olympiads are derived from and extended from the International Mathematical Olympiad (IMO), the International Physics Olympiad (IPHO), the International Chemistry Olympiad (ICHO), and other internationally influential secondary school subject competitions that attract millions of young students every year. The reason for such widespread attention lies in the strong innovation, flexibility, and comprehensiveness of Olympiads, as well as their focus on cultivating students' exploration skills and inspiring their innovative awareness—core elements of quality education. This is precisely what future development requires.
Based on years of careful research into this activity both domestically and internationally, as well as a vast number of outstanding books in this category, the Editorial Department of Primary and Secondary School Subject Olympiads has invited outstanding educators dedicated to this field from across the country to compile and publish a series of books on mathematics, Chinese, English, physics, chemistry, biology, and information technology—seven subjects in total, with over 200 varieties. In terms of variety, quantity, and quality, our Olympiad books are the most influential among peers both domestically and internationally and hold the greatest charm in the hearts of primary and secondary school teachers and students.
The purpose and characteristics of the "Golden Medal Olympiads" and "Golden Medal Schools" series are as follows:
High: Derived from textbooks but exceeding them. Derived from textbooks means referencing the latest [curriculum standards] of the Ministry of Education; exceeding textbooks means closely aligning with competition syllabi at all levels, ensuring comprehensive alignment in content, question types, and skill requirements, thereby fostering interest, developing intelligence, and enhancing abilities.
Accurate: Scientifically precise, with a well-structured layout. Each book is designed according to the characteristics of the subject, scientifically organized, and follows a progressive principle, offering in-depth yet accessible analysis and comprehensive, detailed problem-solving methods.
Innovative: The questions selected are novel, unique, and highly 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.
Refined: Carefully selected examples are challenging yet not obscure, flexible, and achievable. The focus is on generalization and cross-application; multi-solution, multi-variable, and multi-question approaches are emphasized; and emphasis is placed on training thinking skills rather than rote memorization, making learning an interest and hobby.
Renowned: Gathered are distinguished professors, elite teachers, subject leaders, and famous Olympiad gold medal coaches.
Comprehensive: The series includes the following 12 sets, totaling over 200 varieties:
1. Golden Medal Olympiad Entrance Textbooks (ABC Editions): 2 pre-school textbooks, 2 lower-grade textbooks, and 2 lower-grade ABC editions.
