Overall, I'm pleased to have had the opportunity to do the course on line! This allows people to take the course at their own pace. I have many experiences in life and actually operated a small pleasure craft as a kid growing up before licenses and boater safety courses. Also, 38 years military service (army) not at sea! This was a lot of information to hoist in during the various modules. So spending time on each lesson was not a problem as I certainly did not want to rush through it! The inability to review lessons and incorrect quiz questions is quite a problem. One can correct mistakes in life by learning from past mistakes. I never knew which answers were wrong or more importantly what was the right answer? In the end I successfully completed the course on first attempt but still don't know which questions were incorrect?? Boatsmart should try to correct this flaw. You can still make someone do a module over if failed but why not help in the learning process. Thanks.
