I want to list my steps in preparing for the exam.. 

- reading PMBOK 2 times (never ignore PMBOK) + making notes

- reading RITA book 2 times, answer the questions after each chapter + making notes

- try to answer questions online from Pmzilla, Headfirst and Lehmann.

- keeping your notes with you everywhere is very helpful, (e.g you can review the notes during waiting time in the car).

- do the exam and pass.

wish you all good luck..
