This is a set for the Common Test (university entrance exam) preparation, including textbooks for Politics and Economics. It comes with answer explanations. Since I chose Ethics, the books are new and unused, but there may be some minor creases, scratches, and stains. The areas that are blacked out have my name written on them, and if you purchase the set, I will carefully cover these areas with a marker pen more thoroughly than in the photos. I am open to reasonable price negotiations. - Title: Common Test Practice Questions 2026 I English [Reading] - Publisher: Kawai Publishing - Subject: English - Type: Question book - Title: Public Politics and Economics - Publisher: Kyoiku Shuppan - Subject: Politics and Economics - Type: Textbook Thank you for looking.
