This Forum is really help-full. Giving details in Brief.

Go with Question list mentioned in PMZILLA. Questions over there are good. I have visited 50% of them.

As much number of test you will take,that much you will take your concept will be clear .

Go by notes section mentioned in PMZILLA.

Exam required good amount of study.So I read below books almost 3 to 4 times.

1) PMBOOK
2) Rita book

3 to 5 months preparation with regular dedication of 4 to 5 hours is required.

Question made you think. None of the questions will match with above links but pattern will match. Go through PMZILLA tough questions. That made you to think and IT will make your concept more clear. Rita Chapter end questions are also good.

Thanks PMZILLA.
