The main content written in this vocabulary book is Japanese history, biology, world history, etc., which I used for university entrance exams and civil service exams. I compiled important parts from various teaching materials and past exam questions into this vocabulary book. During the exam period, I made sure to study this vocabulary book during my free time, and there were even questions that appeared on the actual entrance exams from this vocabulary book! ✨️ I successfully passed a private university and then passed the civil service exam, so please use it!!
