This book is extremely useful, as the FE exam is based on rapid recall of fundimentals, not in depth knowledge or detailed problem solving. It is very well rounded and is designed to help you brush up on areas where you are weak. As a Chem E. it was necessary to learn the basics of circuit design, statics, etc. and this is the book to do it. The book is laid out in simialr order to the NCEES reference manual, so no surprises on exam day. Remeber, you only have to PASS, you don't need to ace the exam, so the book's few weaknesses won't hinder you from passing.
