I PASSED!!! I was a nervous wreck working toward my license — I wasn't expecting this to be one of the most practical and useful exam resources I've ever come across. It teaches you how to navigate the NEC and work through difficult questions with confidence.

My wife has been an ACT tutor for about 6 years and she's usually pretty critical of prep books. To say she was impressed is an understatement. The book is great, but the online resources that come with it are second to none.

So far this is the best study guide I have found! The study materials are very complete and the exam simulator is pretty good. Still better than any of the others.
