Master Electrician Practice Exam, 2020 NEC

Excellent variety of test subjects and questions

The book came in a timely manner and was in great condition.

Numerous questions and answers in the calculations section are wrong / incomplete. Clearly the questions weren't tested before this book was published. Multiple other people have found the same problem.

I bought this book as a supplement to Ray Holder's tests. The issue I had with this book was in calculations section. He tries to give the same questions as whats in the back of the code book. I kept getting answers that were not an option. When I looked at his answer sheet, it said see example in code book. Then, when I looked in the code book, I discovered he left out vital information in the questions and there was no way I was going to get the right answers. Very Disappointed!!!

On the calculations practice exam of the 80 questions. They have 8 that are wrong in some way. Either incomplete info to get the answer or they missed the math or they simply wildly messed up copying an anex D example. Completely unacceptable for study or practice material.
