Once I This is how I passed this exam after 1 week of study:
I downloaded the test topics covered for the exam, full course content. 
Gathered some books and some material available for free.
Buy the textbook and start reading and preparing.

After every practice test session, I was knowing which topics to re-read.
I have taken exam dates once I started getting 92% or more and given the certification exam.
I passed!
