I wrote the PMP exam on 7th May, 2011 ,  and got a PASS on the printout from Prometric.

Gruelling 4 hrs , and test of nerves.

TIPS

1) Giving this exam makes me think if there is a comprehensive/universal source of information for this exam, and looking at the exam I dont think there is..so my suggestion is to get as much info as you can from different sources, but compile it in a simple format you understand.

A week before the exam just refer and memorize from your notes.

2) Remembering ITTOs is critical. Guess work wont take you too far.
