Uh Oh. We should actually try to figure out what #3 actually is.
As I stated before there is tow versions of the book Softcover and Hardcover the PDF we used is the softcover one , but there is an error somewhere in page numbers I think . If someone can get his hand on both versions It would be great . Or else the OP give us some help.
As I suggested earlier, you can use Amazon's "look inside" feature to grab the pages for both versions of the book.
