These are textbooks used during the winter course while attending a major cram school. ■ 2024-2025 Winter Course Textbooks Japanese/Social Studies/Science/Mathematics/English, a total of 5 books + answer key → These are common textbooks for Ren-sei/Senbatsu/TOP classes. ◆ Due to the thickness, these cannot be included together, but since my child was in the TOP class, there are also special selection textbooks for the TOP class, which are listed separately. My child, who successfully passed the TOP schools in the spring of 2025, has filled these out, so there are traces of diligent study. These textbooks, created with the stance of predicting exam questions, were really helpful for the entrance exams!! I think these will be useful for those who want to refer to them or quickly review and prepare. I would like to sell these to those who understand the condition of the items. ☆ No returns, no claims ★彡
