NCEES material is a must have. I used the guide in question and found it very helpful. Listed below is a review I actually posted in Amazon and which can also be found in the "Testimonial" section of the book's website. I also took the Georgia Tech course and used SpinUp and ComplexImaginary materials. In addition to the internet and YouTube.

However this book is an excellent complement to use with a more formal course and other resources which focus on multiple sample tests. Great sections on circuit analysis, motors, power system performance and protection, etc. I discovered this book about a month before I took the April 2014 exam and it was invaluable in giving me that final boost of confidence which led me to pass. Alex Graffeo is very accessible and proactively sends out corrections. I recommend."[/COLOR]
