Hi,

 

So heard that the author of this pmp study guide is temporarily giving away copies of his guide, which goes through the nine knowledge areas, formulas, ITTO and so on.

 

It normally sells for $20.  In exchange, though, I think he asks that you look over it and respond with a few sentences of feedback (“This study guide is full of helpful material to master the PMP exam” that sort of thing) within a day of getting it.
