Query: Inferior reference

I know the authors worked hard to assemble the information, but the volume of work makes it difficult to accurately write a book of this magnitude. (4 exams in one)It shows. The book was so replete with errors, technical inaccuracies, omissions and irrelevant material, I stopped reading around chapter 5 and used the MS self-paced book.But all that's moot anyway - any preparation material for the 70-240 exam is rendered irrelevant after Dec 31, 2001.
