〇 Pass the exam on your first try! This is how you understand the Grade 2 Boiler Technician Exam, 3rd Edition 〇 Boiler Practical Skills Text 〇 Boiler Picture Book This is a set of three books. I bought these about a year ago, but I no longer need them after passing the exam, so they've been sitting on my bookshelf and I'm selling them. The Boiler Practical Skills Text and Picture Book have many red lines and notes on the parts the instructor said "will be on the exam," and the handwriting is messy. Please refrain from purchasing if you are not comfortable with this condition. Regarding the Pass the exam on your first try! This is how you understand the Grade 2 Boiler Technician Exam, 3rd Edition, there are no notes, but it has creases, so please be aware of that. Honestly, I was able to pass the exam without any problems using just this one book. The books are already packed, so I will ship them immediately after purchase, so please consider this if you are in a hurry.
