"Mastering This: Prevention Technology Certification Exam (Revised 2nd Edition)" Ohmsha Price: ¥3,300 (tax included) New, unused I passed the exam before using it, so I didn't use it. There are no markings or highlights. Since it's stored at home, those who are concerned should refrain from purchasing. Please read my profile. #Ohmsha #book #CivilEngineering/Architecture
