This is a junior high school textbook for cram school use. It is not available for purchase in stores. Recommended for entrance exam preparation. *I am selling this because it was very helpful in last year's entrance exams. It has been used, so there is a feeling of use, but math is not filled in, while social studies and science have writing in them. Please understand and purchase if you are okay with this. All three books come with answer keys. Although they are in very good condition, please refrain from purchasing if you are very concerned about the condition.
