"2021 University Entrance Common Test Strategy Review: Chemistry Basics & Chemistry" Kawai Publishing Editorial Department Price: ¥980 #KawaiPublishingEditorialDepartment #Books #Science/Chemistry This is a reference book. Some parts have been highlighted with a marker, but otherwise, it's mostly unused. The book is designed so that the questions and answers can be separated, and they have already been detached. I checked it myself and didn't find any other major writing, but please be aware that there might be something I missed. I think it's perfectly usable for studying."
