Hi, Peter.
I myself practiced for this exam with the Whizlabs Exam Simulator. It comes with 8 or 9 different practice mock exams, 1 final exam, 1 diagnosing exam and 1 Customizable exam. It comes with about 850 different questions.
It will certainly teach you many mistakes you might make in the exam. Although, at the end, the real exam is easier than the ones that come with the simulator. And Whizlabs offers you 150%
Test Pass Warranty!
Well, I just can say it worked for me.
