I love the setup and the game quizzes.

I am loving it. I think it is very useful for the overall prep.

excellent customer service and fast shipping!

I had a great experience overall. I hope they correct the errors I sent for review.

It was a very good review and would highly recommend for anyone needed to study for their certification test. I was through informative, and the questions were comparable/similar to ones on the test. I passed 1st time and definitely do not have any regrets in trying this a study material/preparation. The best thing is the price was affordable and able to get me to where I want to be with no regrets.
