Features: The subject Olympiad for primary and secondary schools (briefly referred to as the subject Olympiad) is a competition activity for primary and secondary school students in China that covers the widest range, has the largest number of participants, and has the greatest influence. The subject Olympiad draws inspiration from and extends the International Mathematical Olympiad (briefly referred to as IMO), the International Physics Olympiad (briefly referred to as IPHO), the International Chemistry Olympiad (briefly referred to as ICHO), and other influential subject competitions for secondary school students worldwide, which are admired and followed by 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, which are precisely the core content of quality education. This is also the need for future development. Based on years of careful research on 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 reading materials titled "Golden Medal Olympiad" and "Golden Medal School," covering a total of more than 200 varieties in seven subjects: mathematics, Chinese, English, physics, chemistry, biology, and information science. In terms of the variety, quantity, and quality of our Olympiad books, they are considered 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 compilation purpose and characteristics of the "Golden Medal Olympiad" and "Golden Medal School" series are as follows:
1. High: Derived from the curriculum but exceeding it. Derived from the curriculum means compiling in accordance with the new [curriculum standards] of the Ministry of Education; exceeding the curriculum means closely aligning with the competition syllabi of various levels, ensuring comprehensive alignment in content, question types, and ability requirements, thereby cultivating 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 progressive principle, offering in-depth yet accessible analysis and comprehensive, detailed problem-solving methods.
3. 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.
4. Selective: Carefully chosen examples are challenging yet not obscure, flexible, and achievable. The focus is on learning from one example to understand many, and on solving one problem in multiple ways, transforming one problem into many, and asking multiple questions about one problem. Emphasis is placed on training thinking skills rather than overwhelming students with practice problems, making learning an interest and hobby.
5. Renowned: Gathered by famous teachers and collected from prestigious competitions. The Editorial Department of the Subject Olympiad for Primary and Secondary Schools has invited renowned professors from top universities, distinguished teachers from key secondary schools, senior teachers, subject leaders, and famous Olympiad gold medal coaches to jointly compile these books.
6. Comprehensive: This series includes the following 12 sets, totaling more than 200 varieties:
