"2023 Edition Building Management Technician Exam Model Answer Collection" Price: ¥2300 I am selling this because I plan to pass the exam this year based on my self-scoring. There are check marks such as ◯ and × at the beginning of the questions, and some writing in a few places, so please check the photos before considering purchasing. The condition is relatively good, but it is a used book, so please refrain from purchasing if you are concerned about the condition.
