Purchased a few years ago (stored by a non-professional). Both have only been copied, and neither has any writing inside. As shown in the photos, the past exam questions have been separated from the problem set. The Target 2200 book also includes the red sheet. (I'm also selling other textbooks and social studies materials, so please take a look. Bundling is also possible #OchazukeTextbooks #OchazukeSocialStudies) Thank you.
