Not necessary for oral exam preparation
on August 20, 2014
I purchased this book to study the oral questions for my powerplant O&P exam. I never opened it. I studied the oral questions in the ASA test guides and the Jeppesen oral questions in the Quizzlet program. I only missed three questions on the general and powerplant questions. It is good reference material, but it is not necessary to study for the O&P. I think this book was discontinued a decade ago. Save you money. Use the ASA Test guide and Quizzlet program with the Jeppesen oral questions.
