Managed to pass the PMP exam yesterday 3/1/2013 in myfirst attempt! Never been so relieved.

About my preparation:

Read PMBOK 4 once and listened to theRMC (Rita) audio cd's twice in the car. I thought that the latter were very helpful.

Did every free trial exam that I could lay my hands on (most of them are mentioned here at PMZilla) and just kept on practicing. Found the Oliver Lehman and PM study very useful.
