"Foresta" textbook. This text was created by thoroughly analyzing school tests to improve grades. A separate answer booklet is also included. There are likely some markings, as indicated by the red marks in image 3. Also, there are some writings on the homework sheet on the last page, but I don't think there are any other significant markings. I apologize if I missed anything. There are traces of a name written on it. There are some scratches on the cover, but it's relatively clean. Please check the images. 【What is Foresta?】 ・The Foresta series is a textbook for cram schools created to "really improve grades" by thoroughly analyzing actual classes. ・Every year, they thoroughly analyze tens of thousands of regular tests nationwide, identifying what kind of questions are asked and where students make mistakes. ・From the content of the explanations and the selection of problems to the quantity of problems and the arrangement of each question, everything is carefully created to improve grades. Please make your judgment based on the images. If you would like to see any other parts, please feel free to comment. This is a used item. If you are concerned, please refrain from purchasing. Please see my self-introduction. Thank you very much. (m(_ _)m)"
