Shin Chugaku Mondai-shū (New Junior High School Problem Collection) Mathematics Year 1 Standard Edition With Answers Kyōiku Kaihatsu Shuppan (Education Development Publishing) As shown in the fourth photo, there are pages with pencil markings. The markings are only dates and check marks, and there are no answers written. The markings have been erased up to the middle of the book. I used a copy of the book, so overall it is in good condition.
