I also continued to used this book and also found a number of errors in the pictures. This cost me a few points on tests and quizzes, so this added to my low opinion of this book. I also became hesitant to trust what it was telling me, particularly when there were differences between Campbell and this book.
It has a nice layout, and it breaks topics into meaningful chunks; the explanations were okay most times and simply inadequate too frequently for me. On a scale of 1 to 10, this book is about a 3 or 4 and Campbell is a 9. But reading Campbell also takes more time and effort.
