The new edition is available at bookstores, but would you like to solve problems from older years as well? This is a very clean book with no writing or markings. It contains three years' worth of past questions from 2019 to 2021. This is a very good problem collection for those taking the Faculty of Engineering at Tokyo University of Science. "Tokyo University of Science (Faculty of Engineering - B Method)" Kyogakusha Editorial Department Price: ¥1980 For those who understand that this is stored at home, thank you. #UniversityEntranceExam #Akahon (Red Book) #TokyoUniversityOfScience #PastQuestions #ProblemCollection
