In the process of reading it to prep for my certification test, I found multiple problems with it. You can still pass using this book, but the experience will not be pleasing.I'll list them as best I can.
--Different chapters list different minimum requirements (DOS3.3 vs DOS4.0) for the same module.
--The last few chapters of the book have multiple errors in the self-test answer keys. They are obvious things like Right- A, C, D and Wrong- A, C, D or their descriptions a few pages back contradict the answers. At least one of the electronic practice test questions is the same way.
--After a few runs through the electronic practice test, it's painfully obvious that it is repeating the same questions in the same order every time, not grabbing fresh questions from the question pool for each run or installation. So far their tech support has not replied on this. (original email sent in second week of December)
-- The "Update" link provided in the enclosed software (for test 220) takes you to the publisher's web page for test 218. This page shows that there are no updates available, even though the CD came in a book for the next version of the test. I was unable to find any mention of the 220 test on their website.
---- these items are more aesthetic than technical, but contribute ----
---- to the overall dissatisfaction inspired by and in this book ----
--The wording and emphasis of the book does not match up to the actual test questions.
--The material covered, both in a chapter and overlapped between chapters is laid out in a stumbling and awkward way.
--The "drivetime" audio tracks on the included CD were read by an engineer, not proper audio talent. I found myself subconsciously tuning out the annoying voice.
--The quality (tone, volume and clarity) of the audio tracks was not consistent and one was quite bad.
