This is a set that helped my child pass a highly competitive (over 7 times the acceptance rate) integrated junior high and high school in just one year of studying (starting around this time before summer when they were in 6th grade). My child's school test scores were poor until they decided to take the entrance exam, and they had focused almost entirely on sports, so I was about to give up, but they passed safely with this set. There are 32 books, each with an answer and explanation book. Please understand that there are names written and notes in the books. I recommend this set if you can accept that. Entrance exam cram schools cost a lot of money, so I think this set is a great deal if you work hard with it! Integrated Junior High School This set is for aptitude test-based school preparation. The cram school my child attended was a popular school with the top passing rate, and the teaching materials are excellent. If you're thinking about taking the entrance exam but feel it might be a little late, I hope you can do your best with this set. I am also listing this on other sites, so I may remove the listing without notice. If you are interested, please consider it as soon as possible.
