This is a reference book for junior high school students. I purchased it because I decided to take the university entrance exam after working as a member of society for a long time, and I needed to relearn from junior high school. The book is designed to make it easy to understand, with explanations in the form of conversations between teachers and students on areas where students tend to stumble and important points, allowing me to easily grasp the material even after a long break from studying. Practice problems are also included, making it easy to identify areas where I didn't understand. I am selling it because I passed the exam and no longer need it. I think it will be helpful for children's regular studies and for adults relearning as well. I have read it several times, but there are no noticeable folds or damage, and the condition is good. Please refrain from purchasing if you are sensitive to used items. No claims and no returns are accepted. I try to ship as soon as possible, but shipping may be delayed on weekends, holidays, and during the New Year holidays. List price: 1400 yen
