This is the 2021 edition of the Akahon (red book) for Rikkyo University's general faculty entrance exam (excluding the Faculty of Science). There are no markings on the pages containing the questions, but there are a few instances of writing and highlighting on the pages with the answers, as shown in the image. Since these are on the answer pages, they shouldn't interfere with solving the questions. Please consider purchasing only if you are not concerned about this.
