This is "Foresta." It's a textbook created by thoroughly analyzing school tests to improve grades. It includes a separate answer booklet. There is some writing on a few pages, as shown in the images. Also, there is writing on the schedule on the last page, but 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. There are scratches and folds, so please only purchase if you are okay with that. 【What is Foresta?】 ・The Foresta series is a cram school textbook created to "really improve grades" by thoroughly analyzing actual classes. ・Every year, we thoroughly analyze what kind of questions are asked on tens of thousands of regular tests nationwide and where students make mistakes. ・We are particular about the content of the explanations and the selection of questions, as well as the quantity of questions and the arrangement of each question, to improve grades.
