This is a past exam question collection, "Zuru-mon," for the Registered Sales Representative exam. I got the impression that about 30-40% of the people at the exam venue were reading this past question collection. The questions are arranged in order of frequency of appearance in the Registered Sales Representative exam, and the explanations are very easy to understand because they use tables and diagrams. It's in good condition because I haven't used it much. I did make some notes, but I've erased them all. I'll include a red sheet.
