Query: Poor substitute for the Real Manual. Don't bother.

This Quick Reference is a poor substitute for the real Reference Manual. The publishers suggestion is that you study from the real Reference Manual, and then use this "quick reference" to work problems and take the exam. That's a very poor idea. Once you know a reference book, stick with it.One significant shortcoming of this book is that it is not "tabbed" like the real Reference Manual, so trying to find the section you're looking for takes longer than finding it in the comprehensive manual. Bottom line is that this Quick Refernce is nothing more than a list of formulas, and it will not be much help on the exam. I think the reason the publisher put this book together was for an "add-on" sale or for people who wouldn't shell out for the real manual. You need the real manual... skip this one.See my review under the Reference Manual for recommendations from someone who just took the exam.
