Thanks to PMZilla for helping in my success.

Am an Average guy, my experience with exam is as follows

50-60% direct questions from PMBOK
10-15% Math (EMV, Contract, communication channels)
20-25% Situational questions (risk + CC, HR+Integ, Closure).

Many websites help on how to answer first 2 sets. 3rd set is the difficult one to face (for me). Gain more experience in answering the situational questions "IN TIME".

It depends on how much fast your mind relates situation to appropriate process. Direct + Math questions define your pass/fail. Where as situational questions define your proficiency score.

You can use PMStudy freetest as benchmark for your preparation

All the Best.
