This is a problem book for elementary school entrance exams from Rieikai. I purchased this in September of this year for the elementary school entrance exam, but I ended up not using it, so it's in new condition. I used other areas of this book. There are many problems similar to past questions from famous elementary schools from 2022-2024, so I think it's a very good problem book for the final preparation. It's also the perfect problem book for those who want to review a wide range of topics before the exam after completing books like Bacchiri-kun Drill. The problems have perforations, making them easy to use. Bundle discounts are available. The second book will be -200 yen.
