I learned about this course from your site. The course is well organized and easy to follow. I have taken the exam almost 100 times with more than 80% passing rate in the past. But I failed the exam twice within three months. So I thought maybe the questions are changed, so I bought your course and studied for another two months. After finishing the course and doing all the practice tests, I got a passing score. thank you.
