A 2025 edition exam preparation book with a comprehensive collection of past questions and explanations. Thanks to this series, I was able to pass both the plumbing and electrical work exams with about 10 days of study. There are no writings, but there are quite a few lines drawn with Frixion pens. (I was the same, but I think you can pass if you focus on these parts.) - Title: 1st Grade Plumbing Work Construction Management 1st Examination Question and Explanation Collection - Year: 2025 Edition - Contents: Past question collection and explanations - Page Count: A thick book - Features: A long-selling, reliable book highly regarded in the field Thank you for viewing.
