I studied the material presented within this book for three weeks prior to the exam and passed by an extremely comfortable margin. I did not find the kind of contradictions mentioned in the other review. This was the only source I relied upon in preparation for the exam.

I have the 10th edition of this book. I'm studying it now for the Series 65 and find myself cursing every 3rd page or so. There are multiple typos, grammatical errors, and mis-spelled words. Even worse, a lot of the text doesn't make any sense. A subsequent paragraph often contradicts its predecessor, for example. I'm waiting until I finish it to call Dearborn's "help line" with all of my questions. It will probably take an hour to get through all of them. I do not recommend Dearborn's publications and wish that someone would kick them out of this market. Dearborn's editors are welcome to hire me to summarize all of the problems I found with this book.
