Based on this text, I passed the 2025 First-Class Architectual Construction Management Engineer (1st Grade) 1st stage exam with a score of 60 points. I started studying around March, using this text for about an hour each day to gain knowledge, and then solving past exam questions. I would review the parts I didn't understand in this text, repeating this process. I passed on my first try after 4 months of study. Because it's a book that can be separated into sections, I carried the sections around and used them at work, etc. It's well-used, but it's perfect for this year's exam preparation. There are some notes written in it, but please use them as a reference for your studies. - Title: Understand and Pass 1st Class Architectual Construction Management Engineer Basic Textbook - Publisher: TAC Publishing - Volumes: Set of 3 books - Content: Easy-to-understand explanations of important points - Color: Pink Thank you for looking.
