All are from the 2021 edition. I've only flipped through them, so they haven't been used, but there may be minor scratches from home storage. Please refrain from purchasing if you are concerned. (Especially for science, there is a dent on the back cover and a small fold on the spine that were present from the time of purchase.) - Target Grade Level: Junior High School - Study Level: From basic to advanced - Publisher: Juken Kenkyusha Thank you for viewing.
