I tried to read through the PMBOOK but  feel too dull and too many things so I decided to stop half way.

Then I went through the Kim Heldman book. This book let me have a grasp on main process group. Anyway, I still feel there is something missing and not complete.

(Well, I went for my 1st PMP exam atempt and failed miserably).

So I went for RITA PMP EXAM PREP, it focus on knowledge area. After finish this, now I have overall understanding of all the 5 processes and knowledge areas.

Now is time to map the knowledge area into the 5 process group. 

At this point, understanding ITTO for Initiating and Ethic will be easy and I score high (>90%) on those mock test at 1st attempt.

So my focus will be on Planning, Executing, M&C and Closing.

CP, EVM and those formula is the easiest once I really understand the concept.

I went back to Heldman book and go through it 1 more time and compile a summary with keywords and  ITTO. That gave me a grasp of what I had studied and understanding.

 Some of the challenges I had:-

With the experience of the exam, my challeges mostly on the Tools and Techniques as I found that Rita and Heldman gave different answer. Especially on the Ethic part.

Another example is those technique involded Analogue or Parametric tchniques....got a few question on that and some question is easy but some are really tricky.

One thing I notice is that M&C and Risk Management question will really go into the details of testing your memory.

for exmaple, a question gave a situation and ask is this a Risk Management or Risk Idetification and I know either this is the answer.
