"2026 University Entrance Common Test Past Exam Review: Mathematics I, A, II, B, C" Kawai Publishing Editorial Department Price: ¥1,430 Thank you for viewing. Purchased around late July. No writing inside. I only read a part of it, but the binding of the past exam review has come loose. There is no problem with using it. Please purchase if you understand that it is stored at home and has been inspected by an amateur.
