This is a problem set for arithmetic training from Noken Center, a major prep school for junior high school entrance exams. It's for 6th graders taking the 2026 entrance exams. Arithmetic training used this problem set throughout the year. There are 5 books of problems and 5 books of answers, for a total of 10 books. It's quite thick in total. I believe that if you work through this problem set, you'll cover the elementary school curriculum. The textbooks alone cost tens of thousands of yen, so I think it's a great deal. Recommended for those attending a different cram school and looking for problem sets, or for those who want to review and rewrite the problems. It includes not only problems but also key learning points. I studied hard with this textbook and successfully passed my first-choice public junior high school. I think it's lucky too! It's relatively clean. I will cover the name with tape before shipping. Please understand that this is used. Thank you for looking.
