This is by far the worst book I've ever read in my college career. Throughout the entire book only two to three main examples are used. Many times the examples are not carried along through the text appropriately and the reader is referred back to previous pages with information that doesn't really help. And, I've found at least one instance where the reader is referred back to an example and then referred back yet again to a different page. Not good.I would give this book less than one star if I could.
