Mabuchi Kyōshitsu Junior High School Entrance Exam Course Japanese and Math Textbooks (with answer keys), Sub-textbooks, Kanji, and Calculation Textbooks (The sub-textbooks do not originally have answers) These were used in 2020 by a child who was then in the 3rd grade of elementary school. Basically, there is little writing. There are markings, dates, and checks in pencil throughout the books, indicating homework assignments. In Math, there are a few pages with pencil writing. In Japanese, there are also a few pages with pencil writing. In the Kanji textbook, there is pencil writing on about 30 pages. The child's name is written. It will be blacked out. Please consider this item as used and pre-owned, as it was used by a child. Thank you.
