Woot! 903/1000 on my CCNA exam!
Sorry, just had to share. I'm kinda stoked right now. 
Wisdom for the ages:- The official Cisco Press books for the 640-801 exam are fantastic.
- The self-test software in the aforementioned books is the work of the devil. It marks things wrong which are right and some of the questions have fundamental errors (that's right folks, now PPP is an authentication protocol that can run over PPP). Get some other form of self-test software.
- Make sure you really know your stuff.
