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 "Golden Medal Olympiads" and "Golden Medal Schools" series, 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. Primary and Secondary School Subject Olympiads (abbreviated as "Subject Olympiads") are the most extensive, widely participated, and influential subject competition activities for primary and secondary school students in China. 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 middle 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—qualities that are at the core of quality education. This is also the need for future development. Based on years of careful study of this activity both domestically and internationally, as well as a large 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 all over the country to write and publish a series of books on mathematics, Chinese, English, physics, chemistry, biology, and information technology, totaling over 200 varieties. In terms of the variety, quantity, and quality of our subject Olympiad books, they are considered the most influential among peers both domestically and internationally and are the most appealing to primary and secondary school teachers and students. The purpose and characteristics of the "Golden Medal Olympiads" and "Golden Medal Schools" series are as follows:
1. High: Derived from textbooks but higher than them. Derived from textbooks means it is written according to the new [curriculum standards] of the Ministry of Education; higher than textbooks means it is closely aligned with the competition syllabi of various levels, ensuring comprehensive alignment in content, question types, and ability requirements, thereby fostering interest, developing intelligence, and enhancing skills.
2. Accurate: Scientifically precise and well-structured. Each book is designed according to the characteristics of the subject, scientifically organized, and follows a step-by-step approach to provide in-depth yet accessible analysis and comprehensive, detailed problem-solving methods.
3. Fresh: The questions are novel, unique, and engaging. They gather the essence of recent Olympiad, middle school, and high school exam questions from both domestically and internationally, representing the highest level of current Olympiads 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 generalizing from one example to many and understanding broader principles; it emphasizes multi-solution, multi-variable, and multi-question approaches, with an emphasis on training thinking skills rather than rote memorization, making learning an interest and hobby.
5. Renowned: Gathered by famous teachers and collected from famous competitions. The Editorial Department of Primary and Secondary School Subject Olympiads has invited renowned professors from prestigious universities, special-grade teachers, senior teachers, subject leaders, and famous Olympic medal coaches to co-author these books.
