This is a booklet for the general administrative position (Mechanical) of national civil servants. I haven't solved most of the mock exams, so they are almost unused, haha. The booklets for Engineering Fundamentals, Numerical Reasoning, and Specialized Subjects were used frequently, so they may have check marks and folds. Please be aware of this. Also, some are the 2024 edition. - Title: National Civil Servant Mechanical - Contents: All TAC 2025 Mechanical position booklets - Publication Year: 2014 - Language: Japanese - Number of Booklets: Multiple - Format: Paper Thank you for viewing.
