At first I was skeptical of the whole doing the modules and quizzes plus writing an examination. Previous people didn't have to do that... But, I found the modules rather informative and the quizzes enforced the material as well. The exam made you think, just wish there were more real life scenarios (ie you have 3 boats coming towards you what do you do, or someone on the boat gets a fracture or starts bleeding due to a cut what do you do, you are looking to anchor quickly due to a coming storm that is unexpected what do you look for... given scenarios and choices.). Scenarios would be very beneficial and learn a lot from them, never know what can happen out there, anything really from someone falling over, to a simple cut to someone having a heart attack, or someone getting run over by a boat... thus, scenarios would allow one to learn and think things through.
