I passed my PMP exam yesterday which is 5th October and would like to share my thoughts and experience here so that it helps someone.

My Preparations:
I took classroom based contact hours from PMStudy last year. They conducted 2 days of classroom training which was very nice. My initial plan was to give the exam in February this year but because of daily laziness it kept moving ahead.
Around starting of August I became serious and decided to lock the date for 5th October.
Among the books I read PMBOK, Headfirst and PMStudy book. I just devoted around 1-2 hours average daily for reading books and read lots of examples of project management from internet. I am watching PMZilla almost daily since this time.

Mock Exam:
I did not try lot many practice tests and just focused initially on PMStudy and then Rita Fast track. Around mid-September I started exploring for free options and liked the questions of PMZest which I brought and took. I liked all these three providers and I would recommend them all since they are great for checking your preparations and they are all different than each other which gives you variations in trying different questions.

About the PMP exam:
Real exam has very conceptual and situations questions. They create lots of confusion when choosing choices (especially 2 choices). Questions on Risk, Quality, and Procurements are seen a lot.
I found very few direct IITO based questions.
Numerical questions were also few, say around 10 on cost/schedule management.
I took one break of 10 minutes but was able to finish the test 20 minutes before time.

Result:
I passed PMP exam with Proficiency in Initiating, Executing and Moderately Proficiency in all others.

My suggestion:
Stick to a goal and decide the PMP exam date and move on it so that you do not waste few months as I did. Reading 1-2 books along with PMBOK is just enough. Take good quality mock test from 2-3 providers only and avoid exploring too many free options. Look for mock test which has learning than high scoring. Think real life on project management examples and this helps a lot to answer PMP exam questions. Around 3 months of time for working professional is sufficient to crack this exam with just 1-2 hours of daily efforts.

Thank you and best of luck.
