This is a set of Administrative Scrivener (Gyoseishoshi) exam preparation materials from Waseda Keiei Publishing, including the Basic Textbook, Basic Problem Collection, and Past Questions by Answer Choice. There is no writing in the books. They show some signs of use, with some folds and bends, but are in reasonably good condition. The Basic Textbook is designed to be split, and has been separated as shown in the second image. I purchased these materials, but I primarily used the online resources of a correspondence course, so I am selling these.
