This is a used red book (akahon) for Teikyo University of Science's 2026 admissions. There are some scratches on the front and back covers, and the edges of some pages inside are creased. (There are no issues that would make the questions difficult to read.) I erased some writing. (There might be some remaining, but it was written lightly in pencil, so it should erase easily.) Thank you for looking.
