This was obtained at a school information session. It can be used for past exam practice, etc. ・Official past exams, answers, and commentaries issued by the school. ・Unlike commercially available materials, the answer examples use actual answers from examinees, and the explanations are very detailed, such as showing the correct answer rate. ・Contains hints for Musashi Junior High School entrance exam preparation, such as explanations of how to solve problems. The problems, explanations, commentaries, and grade distribution are included. Because it was issued by Musashi Junior High School, you can understand what kind of answers are preferred, what the intentions were in creating the questions, and how they are graded. I have used it by making copies. There are no writings, and the inside is in a clean condition, but I have read the explanations, so I think there is a feeling of use. There is something like red ink on the 2018 edition. The back cover of the 2019 edition is dirty. I don't think it will affect usage, but if you are concerned, you may want to refrain from purchasing. Please check the photos. ☆Musashi Junior High School Entrance Exam Questions 2015-2019 (5 years) Booklet 　4 subjects (Japanese, Math, Social Studies, Science) 　Problems (answer sheets) + answers/commentaries included #JuniorHighSchoolEntranceExam #EntranceExamPreparation #PastExams #ReferenceBooks
