Junior High School Entrance Exams: Shin-Enshu Calculation Diary, Confirmation Tests, Arithmetic, Grade 5 (Volumes 1 & 2), Grade 6 (Volume 1) Set of 15 books. My son, who is currently in the first year of junior high school, used these at cram school. There are no writings in the answer sections, but there are some writings in other parts. I have erased the pencil markings, but some ballpoint pen markings remain. All confirmation tests are unused. There is a general feeling of use, such as tears and folds. The answer key for Grade 5 Volume 2 has considerable wear and tear. (No pages are missing) All confirmation tests are unused. Please purchase if you understand that these are used items.
