Title: Very good, but numerous errors
Review: I found the main part of the book to be very good but I expected more for $70. Diagrams/screen shots were weak with errors and not enough of them. Numerous typos and formatting problems that were distracting. Looks like it would have benefitted by one more checking/editing pass rather than being rushed to press. The test section was most disappointing. Some vaguely worded questions, a wrong diagram and incorrect answers. Mastery tests were just self-assessment test repeated.
