Regional Development Institute 1st and 2nd Class Electrical Construction Management Technology Textbook Revised 4th Edition This is from when I took the exam in 2024. Please check the condition of the product in the photos. There are markings and writing (light pressure) on about 10-20% of the book, but there are no folded pages. I am also selling other problem sets, so please take a look if you'd like. Please consider this item with the understanding that it is a used product.
