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 compiled 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 and is deeply loved by teachers, parents, and students. After significant revisions, re-editions, or complete rewrites, it has been renamed as "Golden Medal Olympiad" and "Golden Medal School" 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 (referred to as "Subject Olympiads") are one of the most extensive, widely participated, and influential subject competition activities for primary and secondary school students in China. Subject Olympiads are derived from the International Mathematical Olympiad (IMO), International Physics Olympiad (IPHO), International Chemical Olympiad (ICHO), and other internationally influential middle school subject competitions that attract millions of young students every year. The reason for such 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 and essential for future development. Based on years of in-depth research on this activity and 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, totaling over 200 varieties. In terms of variety, quantity, and quality, our Olympiad books are among the most influential in both domestic and international peers and hold the greatest charm in the hearts of primary and secondary school teachers and students. The compilation purpose and characteristics of the "Golden Medal Olympiad" and "Golden Medal School" series are as follows:
1. High: Derived from textbooks but exceeding them. Derived from textbooks means referencing the latest [curriculum standards] issued by the Ministry of Education; exceeding them 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.
2. 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 comprehensive problem-solving methods.
3. Innovative: Features novel and engaging question types. It compiles 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 innovative ideas, methods, and trends in competition question-setting.
4. Refined: Selects exemplary problems that are challenging yet logical, flexible, and aspirational. Emphasizes the ability to generalize from specific examples and promotes multi-solution, multi-transformation, and multi-question approaches. Focuses on training thinking skills without resorting to rote memorization, making learning an enjoyable interest and hobby.
