I got the required 35 PDUs from PMSoft in year 2010 which was great help but some how could not appear for the test due to personal reasons.

In September this year I registered with PMI and applied for the test. I read PMP® Exam Prep 7th Edition - Rita Mulcahy for about 20 days. I read the entire book except Quality,Risk and Procurement knowledge areas. With 70% preparation I wrote Pmstudy mock exam but got 60 % and 47% in the PMZilla sample question exam. Then from LL of the users here I realized that PMBOK is the key for the success. Then I read PMBOK several times. Downloaded Abhishek's Version - Rajesh Nair PMP Notes and read it whenever I got time. I studied 2 hours in the morning and around 1 hour in office whenever I got time. And on weekend I studied approximately 8 hours. Then I wrote the exams Pmstudy,Oliver,Examcentral and HeadFirst  and started getting 70 to 75% average in all of them. Then read the Risk and Procurement from Rita and I can tell you that it helped a lot because I saw lot of questions in the actual exam similar to Rita on these two topics. I also studied the problems from Rita. So all in all it is Rita and PMBOK together worked for me.

The exam was tougher than all the available mock exams. The questions after each chapter from Rita are good to get the feel of the lengthy and wordy questions from the exam . The exams focused more on practical and day to day work  in different industries e.g. what is discussed in the defect prevention meetings. Also the ITTO questions were not that easy where one could easily separate the odd one out. I got almost 20 problems mostly on EV and few on activity sequence diagrams. Looks like the exam is getting tougher day by day but the key remains the same as told by all the PMPians here understand the concepts.Finally practise lot of wordy questions and when you study ITTO don't even miss reading where EEF is updated, I got question on that also so be vigilant.

All the best.

I had created my own mnemonics for ITTO and other theories but those would be helpful for the indian friends as they are in hindi mostly few in english. If somene interested please let me know.
