A model answer collection containing the questions and answer explanations from the past 9 years of the Class 3 Refrigerating Machine Technician examination. - Title: 2025 Edition Class 3 Refrigerating Machine Technician Examination Model Answer Collection - Publication Year: 2025 - Examination Type: Class 3 Refrigerating Machine Technician Examination - Contents: Questions and answer explanations from the past 9 years - Special Features: Answer explanations are in a separate booklet (not detachable) - Publisher: Denki Shoin - Price: ¥4290 It has been used with a cover, so there is some wear and tear, but it is in a clean condition. Any writing has been erased and is not present. (Apologies if any remain) I used this for the 2025 exam and passed. This one book was sufficient as a collection of past questions! *However, the trends in the questions change slightly year by year, so it is recommended to use newer past question books.* Thank you for looking.
