"I have taught Code classes for ten years and have searched for an easy to understand electrician's exam prep book that covers all aspects of the exam. I have now found one. This book is very comprehensive and yet is simple to understand. The examples provided are very helpful in explaining the step-by-step process to solve the type's of calculations necessary to pass the Journeyman and Master exams. I like that this book has plenty of questions from different Code articles to help users gain confidence in using the Code book. I am now confident that a lot more of my students will be getting their License. I would recommend this book to any one that is serious about passing the Journeyman or Master Electrician's Exam."

Jerry Ray, State Certified Electrical Instructor, Electrical Contractor

“I have used other textbooks in the past by different authors and always find myself explaining the Math portion of the course on my own because the books were either too complex (written for an engineer) or not the right format. Charles Miller’s exam prep book…is written in electrician language (easy to understand). I have now switched to this text for my class and the results are wonderful.”

Scott Pomarico, Instructor, Electric Medic Code Course

“I took my first master electrician test for Tennessee back in 1991, and…passed it the first time. I never dreamed I would have to take another master test again, 17 years later. I was well prepared for both tests by thoroughly studying your materials. And as an added bonus, your study manual is a great reference book for all those questions about the Code.”

Larry W. Pace, Vice President, RG Electrical Contractors, LLC

"Mr. Miller's style of introducing a topic, using examples, and follow up practice questions is a good straight forward approach to teaching."
