"Suken Shuppan New Course University Entrance Common Test Measures Check & Exercise Chemistry" Price: 910 yen + tax This is a two-book set: the main text and the answer key. It includes past questions from the Common Test's main and additional tests, allowing for efficient study of the entire range of topics. It is compatible with the new curriculum. Used only once. There are only two places with writing, as shown in the fourth photo, but otherwise, I believe there is no other writing. If you would like to purchase this along with other reference books, please comment before purchasing, and I will offer a small discount. #book #CommonTest #universityentranceexam #chemistry
