The site is well made, the course as well. The narration is clear and the animations quaint and useful. I found myself learning quite a lot about boating and buoy markers, procedures and emergency tips. My main concern is that every module requires a quizz at the end, and the questions themselves seem to be designed for failure. Too many of them focus on mundane details instead of the more interesting components (which are not lacking!) I passed, but found there was a missed opportunity in the question design. Enough that instead of a five star rating, I give it a three (and a half) stars Otherwise I think there's quite a bit of potential here.
