First time since Vista that I have used one of the MS Training Kit books I have been using the Sybex and R2 Unleashed for 640/642. I'm finding the 646 MSTK book to be such a bore I wanna jump out of a window it's so repetitive it's hard for me to stay focused and prepare the right way.

How is the the 643 and 647 MSTK books the same?
