Iwate University Red Books - Bundle This is a set of 3 books: 2018, 2021, and 2024 editions. It includes problems from 2015 to 2023, allowing those considering taking the Iwate University entrance exam to prepare with 9 years' worth of past questions. No individual sales are planned. Please refer to the images for any writing or stains. If you would like more details, please leave a comment and I will respond. Basically, for books with writing, I've included the most written-in part of each book. For books without individual images, I couldn't fully confirm, but I didn't see any writing. Please forgive any oversight regarding writing. Please refrain from purchasing if you are overly concerned about condition. I will disinfect the book surfaces with alcohol before shipping. Thank you for your understanding.
