Aloha from Hawaii, 

I have cleared my PMP exam on Aug 20th. 

The exam was not easy but not too difficult.

I got to know this website very end of my PMP exam preparation but gave me very good and useful information for my PMP exam. Wish I could find PMZilla earlier. So, I knew better.

Main material I used for PMP is Rita's PMP Prep 6th edition. 

I think Rita's book is good to understand the concept. Especially PMIsm. However, Rita's exam quiz at the end of each chapter seemed too wordy and real exam was not really wordy. Mostly concise.

Just like other people said, PM Study was the closest exam simulator to the real one. I took only one free exam from PM Study but I thought it was good enough to know what real 4 hours exam like. 

I also used brainbok.com to understand ITTO's. It was good for me but PMBOK & Formula test simulator was far away from real exam and found some answers were incorrect. If you want to pass the exam, it is better to stick with something close to real PMP.

Thank you PM Zilla admin and all other people for giving me very useful information!
