I am glad that I have cleared the exam today. A big thanks to this community, which was vital. Here are my lessons learned.

Books used: mainly PMBOK and RITA. Used Head first for some time. RITA made many concepts clear to me.
Training: Used Company provided one.
Mock test: every thing out in web that are free. I believe if you are constantly touching 70+ in the mocks including oliver than you are ready.

Exam is mixture of all kind of questions. So you cannot say this mock is good and others is not.
