Before I share the link to the next Study Guide section, I want to complain a little about the NTC Grey book. I hope you haven't wasted any money on this publication yourself, or if you have, I hope they've improved. I ordered this book in 2013 and was LIVID at how useless it really was. The NTC description is so far from accurate its not even funny. 

Just as the title says, This is a "CERTIFICATION GUIDE", not a study guide for test prep. I expected a large book with lots of useful information and what I got was a book of sample test questions and directions on how to apply for your NICET. 

The book is $150.00 direct from NTC (over priced) and on Amazon and Ebay sells for a little over $200... Haven't figured that one out yet... 

Check out this guys Amazon review...

He seems to share the same sentiment I do regarding this book.. and it seems he way over payed purchasing on Amazon. NTC does not have a way to rate or review the book on its own page so there's no way to warn other designers of what they are really getting.
