Meishinken Elementary School 5th Grade Summer Course Japanese, Science, Social Studies, Math, Math Intensive Training Textbook and answer key set Social Studies: First 2 pages have heavy marking, but almost no writing after that. Japanese, Science, and Math: Some writing in places, but not much. My daughter, who is currently a high school senior, used these. I am selling them because my younger child will not be using them. Thank you for your understanding. #JuniorHighSchoolEntranceExam #Meishinken
