High School Equivalency Workbook This includes 8 subjects: World History, Basic Earth Science, Science and Human Life, Mathematics, World History, English, Geography, and Japanese. This is a set of 6 books purchased together by a successful applicant. Only the Mathematics book has notes written in it by the previous seller (see photo 2). Geography, Mathematics past questions, and Science and Human Life past questions were purchased additionally. Those 3 books are in very good condition with no deterioration. All 9 books have no tears. Past questions for 2 years (2023 and 2024) are also included! Both the previous seller and I passed on the first try. I hope this helps the next person succeed. If sold separately, each book will be 1000 yen.
