This is a checklist of inorganic chemistry topics for third-year high school students from Tetsu-ryokukai (79 pages). The problems are organized into the following three levels, allowing for efficient and effective learning: ★★ Second-year high school chemistry level ★☆ Third-year high school chemistry level ☆☆ Quite advanced level Some important problems have circles or other markings, so please refer to those as well. Overall, the book is in good condition. By reviewing this before mock exams and entrance exams, I was able to stabilize my chemistry scores at a relatively high level, which helped me pass the national university medical school entrance exam on my first try.
