A study guide summarizing the key points of arithmetic specifically for junior high school entrance exams. Units 1 through 11, as shown in the photos, have been written in and marked, but units 12 onwards and the diagnostic tests are unused, so you should be able to use them sufficiently. There is also one page written in the separate answer booklet, and there are some creases. Each unit is organized with explanations and problems on facing pages, making it ideal for checking just before the exam or for getting a general overview of junior high school entrance exam arithmetic problems! - Included: Diagnostic tests to identify weaknesses - Publisher: Nichinoken Thank you for looking.
