• 2 weeks of preparation
• Read Rita's thrice
• 3 mock tests
• Redo the wrong quetions multiple times

I should say I am a very lucky guy but I am glad I was able to clear the test. Rita's book is awesome, it has everything that you need to pass the test. 

Preparation:

Week 1

• Day 1-2: Started with a 2 day fast reading of Rita's book. This gave me an overview of the topics on the test.
• Day 3: Took a mockup exam -- scored 52%, this gave me a basic idea of where I stand.
• Day 4-7: Started detailed study of Rita's book. Took 4 days to complete. Solved all the questions at the back of each chapter, diligently went through all the questions that I got wrong.

Week 2

• Day 8: Took a mockup exam -- scored 64%. At this point I knew I was in a danger zone. I had to bring this up to atleast 75% to be in a comfortable position for the test
• Day 9-10:  Did Rita's for the third time, took two days to complete. But many of the concepts were more clear to me this time. I focused on the topics where I did poorly on the mock test. This was very very very very helpful.
• Day 10-13: Solved many more questions over these 3 days, referring to online forums, youtube videos and Rita's. In the last mock exam I scored 74%. 

Exam day:

4 hours was very very long and it was difficult to stay focused all along. But some tips

• Average 1 minute per question, not more than 3 minutes on a question
• Mark the questions. Some questions are clarified as I was answering others
• Use 4 hours

This was my score

Initiation -- P

Planning -- M

Executing -- P

Monitoring & Controlling -- P

Closing -- P

Once again, I would say I have been lucky. 2 weeks is a short time to prepare for this test. Questions on the test are very situational. Real experience and knowledge on the subject is very essential to get the questions right. 

Gook luck :)
