Hi Vikram,
Sorry to know that you did not clear the Exam. Don't loose hope, you will clear it !
Please go through my post in the 'Lessons Learnt' section of the forum for quick tips and suggestions for PMP exam preparation. In short, if you have already not bought a simulator, please do buy Prepcast Simulator asap. There are plenty of good questions (2100+) for practice including 4 full length practice exams. The quality of the questions on the simulator will enable you to learn key concepts quickly. All the best !
Regards,
Swapnil Bhardwaj
