Features: This book has the following characteristics:
1. In terms of chapter arrangement, it is meticulous yet not cumbersome. For example, the chapter on chemical calculations is divided into four major topics: calculations involving chemical formulas, calculations involving chemical equations, calculations involving concentrated solutions, and comprehensive calculations. This classification is simple and concise, while also providing a macro perspective on the basic types of calculation questions encountered in the junior high school entrance examination (JSEE), making it clear to students at a glance.
2. In terms of the arrangement of question difficulty, it is done in a gradual progression from easy to difficult, from simple to complex, and step-by-step improvement. This allows students to smoothly accept the difficulty level, leading to gradual improvements in their performance.
3. The book also puts considerable effort into the arrangement of difficult questions. The selected difficult questions often focus on analyzing complex given conditions and the application and transfer of fundamental knowledge learned in class, emphasizing the examination of students' analogical reasoning abilities. Additionally, extracting useful information from new materials to enhance the ability to solve new problems, as well as developing psychological resilience in the face of complex problem sets. These assessment priorities reflect the core spirit of quality education—rooted in the textbook but exceeding it, with a focus on cultivating various abilities.
4. For the two key JSEE topics of experiments and calculations, the book effectively grasps the difficulty level of advanced questions. Since these two areas are major indicators for differentiating student performance in the JSEE, students must focus on them to achieve higher scores. Many of the experimental questions in the book are adapted from senior high school exam formats, and they also touch upon knowledge that students will soon learn in high school through information-based questions. This helps broaden students' horizons and expand their knowledge base.
5. For calculation questions, each problem is accompanied by explanations, and every step is backed by reasoning, making it very convenient for students to self-assess and review. It is evident that this book is indeed a treasure trove for junior high school students preparing for the JSEE.
