"Basic Science Problems for Junior High School Entrance Exams, 5th Grade" Nichinoken Curriculum Department Price: ¥900 I've lost the cover, but it's new and unused. The beginning has explanations of the units, followed by practice problems in order of difficulty. I think it's a very good textbook, but I won't be using it because I've decided to attend cram school. #JuniorHighSchoolEntranceExam #AdvancedLearning #Workbook #Textbook
