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.

always good to work with

easy to get to

i love it
