A great deal on a set of 4 red books (Akahon) for private science, engineering, and technology departments. This is a bundled sale, a set of red books. It's a bargain for those aiming for the science and engineering departments of private universities. The following are the universities whose past exam questions are included in these red books: Shonan Institute of Technology, 2023 edition Nihon University, College of Science and Technology, 2021 edition Shibaura Institute of Technology, Early Period, English Qualification/Certification Exam Utilization Method, 2023 edition Tokyo City University, 2022 edition All books are in clean condition with no writing. Apologies if I missed anything. However, these are used books, so please refrain from purchasing if you are sensitive to this. Thank you for looking.
