Hello everybody, the chapters to study for the final WAN exam are:
CCNA4 book : Chapters 1,2,(Part of 3),(Part of 5). I for myself, found many things that weren't on the slides, so I didn't study them for the book.
the rest of the stuff ( chapters 6,7,8, and 9) are from the slides on the cms and the hard copied Book from the bookstore which includes Chapters 6 ( routing and routing protocols),
and 7( Distance vector protocols).
Best of luck.
