Hi,

Just want to share with you that I use www.examcentral.net to prepare for the exam. This is a great source one because it is free, second because it give a full access to almost 1000 mock questions, flash card and dictionary. This exam almost close to the real exam and could help you to build confidence in doing exam.  If you score above 80% with more than twice using this practise exam, means you are ready.

Good luck.
