Purchased here and used once. I confirmed some errors with the seller and have made corrections. These are memorization cards for the Yotsuya Otsuka and Waseda Academy pre-series textbooks, organized by curriculum unit. Thanks to these, I was able to maintain my SS ranking. 【Card Contents】 Grade 4, Volume 1, Social Studies ・Lesson 1: Healthy and Comfortable Living: 48 cards ・Lesson 2: Jobs that Sell Things: 48 cards ・Lesson 3: Life in the Past and Life Today: 48 cards ・Lesson 4: Prefectures and Regions (1): 58 cards Grade 4, Volume 1, Science ・Lesson 1: Magnets: 48 cards ・Lesson 2: Insects: 58 cards ・Lesson 3: The Work of Flowing Water: 48 cards ・Lesson 4: Seasons and Weather: 48 cards Card Size: 60mm (height) x 105mm (width) *Rings are not included. Instead of one question per card, there are multiple questions. This is to help you learn the material comprehensively, as memorizing individual points can be easily forgotten. The arrangement of the questions and the one-point information on the back are designed to broaden your knowledge and understanding of the underlying concepts. The following are the precautions stated at the time of purchase: ・Each card is handmade. ・The card units are based on the pre-series units, but each question is created independently. Therefore, there may be differences in wording or slight deviations in scope, but we believe they are effective for actual test preparation. ・They are produced using a home printer, so there may be some printing misalignment or blurring. ・Proofreading has been done, but there may be typos or errors remaining. Please purchase only if you understand this. Regular price: 8800 yen Waseda Academy, Waseaka, Curriculum Test, Qualify Test, Grouping Test
