The only reason that i could not give this course a full rating is that I believe quite a few of the questions irrelevant to safe boating. The content I am speaking of is question like 'Who made the law about such and such, etc.'. I personally believe who decided the rules is irrelevant. Who enforces, I believe is important (who you will be crossing should you not follow laws and rules). Mostly though i would like to see less of who decided the legalities of everything and focus more intently and correctly identifying real-world markers, speed zones, buoys, and so on. The kind of stuff that will actually save lives out on the water. Just my two cents, thanks for the course and license though!!
