This is the original entrance exam questions from Kyoto University. A set of 4 books, covering the years 2020, 2021, 2022, and 2023. Science subjects only. Studying past papers with Akahon (red books) is fine, but why not study with the actual entrance exam questions? The back cover of the 2020 edition has some stains, so it's included as a bonus.
