Features: While the "Longmen Special Topics" series selects a large number of questions, it absolutely avoids the practice of simply changing numbers to present them as new ones. Although the questions are challenging, the difficulty progression is well-structured and not just a simple combination of end-of-book problems and olympiad-style questions. Although the "Longmen Special Topics" is primarily aimed at students taking the national exam, it also covers all the essential topics of the Shanghai exam, with slight enhancements—this aligns perfectly with the traditional style of the Shanghai college entrance exam. In summary, this series provides a solid and effective path for preparing for the college entrance exam. If, in addition, a teacher guides the selection of the most important examples and exercises, and students who have chosen the "Longmen Special Topics" can collaborate with each other, then it would be almost perfect. I believe that a good reference book must first and foremost be well-organized, highlight key points, and explain concepts clearly. Reference books are meant to supplement textbooks, not simply repeat them. The "Longmen Special Topics" series, based on textbooks rather than merely repeating them, divides the knowledge of subjects like mathematics, physics, and chemistry into many knowledge points and blocks, organizing them into separate volumes for summary and. This is highly suitable for targeted review and systematic reinforcement of knowledge during regular study.
