Query: Wait for another book

What the other reviewers have said are completely true. There are too many errors in this book for it to be of any value. I found myself referencing what they were saying with other books as I had no confidence at all in their text. The test engine is not of any use either. I got the same question 10 times when I tried the engine. Save your money and wait for another book to come along. I passed the test but it was with the help of the Transcender sample exams.
