This is a Shinken Zemi educational material set. I have lost only the science memorization book. Review for 1st and 2nd year of junior high school is also possible. A perfect set for regular tests and entrance exam preparation. - Title: Regular Test Memorization Set - Title: Pass Memorization Technique - Title: Comprehensive Review BOOK I withdrew from Shinken Zemi after two months of enrollment, but the English memorization book has signs of use due to being used during travel, etc. The others are in good condition. I got all 5s in school only by using this and my school studies. I plan to list a set for entrance exam preparation as well♪ Thank you for looking.
