Navista NEXT Navi Kobetsu Shido Gakuin (Navi Individual Tutoring Academy) Exam Preparation Course High School Entrance Exams Purchased in September 2025. All 5 subjects are included. All 5 subjects have answer keys and pre-checks. 4 subjects are unused, only math was used. There are no writings or markings in any of the 5 subjects. There is a small stain on the cover of the math answer key. Please check the photos. Since I have finished high school entrance exams, I am offering this to those who need it. I purchased it at the cram school for 13,850 yen and used only math for 5 months. This is a used item. Please purchase if you understand this.
