Junior High 3 I-Work All Subjects Set: Math, Japanese, Social Studies, Science, English All with supplementary problems from I-Work Plus. Used for the 2022 academic year's entrance exams. The Social Studies and Science materials have some markings, such as underlines and checks for incorrect answers, as shown in the third photo. I believe this won't hinder your ability to solve the problems. I have checked them, but I apologize if I missed any in the other subjects. The answer sheet for Social Studies has a tear that has been reinforced with tape (see photo 2).
