This company has not a clear training and question on the final exam are not related to the course material. They allow you to retake an exam two times for the price of the course, but when I was purchased the course they said that you can retake an exam as many times as you want. But the actual they meant that you can retake a practice exam many times, not an actual exam. And I passed a practice exam with the pass score, but the actual exam was separated for three different sections and I passed two of them for the score more than 90%, but one part for the score that is less than 70%, and it means that I have to retake this one one more time without explanation where I might have mistakes. And after retake the part one more time, I got the absolutely the same results as before. Questions formulated are not clear and after I haven't pass the second time, they asked me to pay $300 more to retake an exam. I do not recommend to use this company to anyone!
