When it comes to workbooks, "Eiko Work" is a major, highly reputable textbook used by many. It's a well-balanced textbook in terms of font size, space for answers, basic explanations, and problems. Above all, it's an easy-to-understand text from the student's perspective. The text supports both class preparation and test preparation, and I think it will be a good opportunity to develop a study habit. Please use the "Confirmation Test" for test preparation. This is a textbook exclusively for cram schools, compliant with the 2025 textbook revisions. Brand new, unused. Please be sure to check as the textbooks used in each municipality and school nationwide differ. The math textbook corresponds to Tokyo Shoseki. Thank you for viewing.
