Really enjoyed the ease of signing up. I really enjoyed the different options to take the course on-line. Having the option of reading or listening or watching an animated subject material. I believe it allows for different learning abilities. Each module was well defined and easy navigation on the web-site. the dashboard made it easy to track performance. All in All, it is a great solid course, with printable reference material to keep handy when you are getting ready to go out on the water. Do yourself a favour, spend the $20, for the book as there is no way you can remember all the rules and tips and safety measures.
