This is a very easy to read and understand book. I used it to prepare for the Series 65 Exam. It was the first securities industry qualification exams I have been to. Robert Walker's materials are the only ones I used. And I passed the exam from the first time. I do not have formal business education. Have you looked at statistics - how many people with business education fail this exam?
The text is not only particular and helpful with the exam's subject but is also written in a very friendly in times humoristic character that makes you treat this book as you sofa side evening reading (well, ok, not after the actual exam was taken).
The book specifically makes good jokes about certain non-sense oddities of the exam. Those jokes actually helped me a lot to remember certain test question scenarios that one will not remember or even figure out if they try to read from a business/economics text book.
Thank you very much. The most important thing - I passed the exam from the first try.

Over the past 20+ years, we've tried all of the other test preparation providers(Dearborn, Passtrak, et al). Our registered reps have scored much higher on exams, have spent less time studying, and have much better retention of the content even months AFTER taking the exam using the Passthe65, Passthe63, and Passsthe6 materials. A significant educational breakthrough which has resulted in major time and cost savings for our firm.
