Passed 70-620 a few days ago.

Got a score of 803. Only resource used was the MS Press Book. I failed the first time. Had 65 questions and about 7 simulations. Be sure to know about: networking (biggie), types of backups, windows sideshow, windows sidebar, power settings, and of course system requirements (what you need to run Aero and how to diagnose it).

Had only 1 question about Tablet PC's and 1 about networked projectors. Onto 622 now. I know I could of taken just the 621 exam, but it seemed too much information for me to try and remember.
