Hi All,

I'm in the midst of preparing for the PMP exam. Most of the time, I will stuck in the jam travelling to client's site. Thought f fully utilising the time when in the car.

Any recommended audio book which is inline with PMBOK guidelines?

Currently I had:

PMBOK4

HeadFirst

Rita Mulcahy 6th edition

Do I need any other book along with the above for preparation?
