I have to admit that I was reluctant to purchase your course. I found several sites offering quick study and practice exams, but based on previous flying lessons from years ago, I found most of their content was inaccurate and sometimes very misleading. I finally took the plunge and enrolled this morning knowing that you offered a 30-day money back guarantee and I must say that I’m glad I did. The videos are very clear and content is very informative. I am impressed.
