Thank you for viewing. I purchased and used this last year. As you can see in the photos, there are pencil markings and notes with answers throughout the book. I apologize for this. Also, please note that the listening audio download period (until August 31, 2025) has passed, so you will not be able to practice the listening questions with the book alone. The separate answer booklet (already detached) and the answer sheets are included. Thank you for your understanding. Obunsha Price: 3080 yen
