Shinshu University Faculty of Engineering and Faculty of Agriculture, Early Period, Akahon (Red Book) - Bundle Set of 3 books: 2017, 2020, and 2023 editions. These contain problems from 2014 to 2022, allowing those considering taking the Shinshu University Faculty of Engineering and Faculty of Agriculture entrance exams to prepare with 9 years' worth of past questions. No plans to sell individually. 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 images of the most written-on parts 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.
