Learnt a lot of good information. I would recommend this course. After each module there is a quiz. If you fail the quiz you need to go through the whole module again. I would suggest a summary review of the module for one re-quiz attempt and if you fail again then there is a requirement to review the entire module. (If I remember right there are about 7 modules from 30 to 50 minutes long) I needed to take one of the modules over again. Overall a pretty minor issue, the benefit outweighed the negative. I have never been a boater previously so I was amazed by the amount of information provided. It has and will make me a safer boater on the waterways. Lastly, I really enjoyed the on-line experience.
