As a canoeist and kayaker for decades who now wants to qualify to drive a PWC, I learned lots of good information that will stand me in good stead whatever water craft I am using. I'm grateful. That said, I found the course and quizzes frustrating for two principal reasons. Many of the videos did not work. That unnecessarily complicated the exercise. In addition, it would have been helpful to have been told what quiz questions I answered incorrectly and what the correct answers were to those questions. It would have added to my learning. While less significant of an issue, it seemed to me that given the increasingly high definition images we are used to seeing on our screens these days, the visual appeal of this course could be greatly enhanced. All of that said, thank you for providing this service. I'm truly grateful.
