I'm glad we went with BoatSmart for our boating course and exam. I purchased them on a 40% deal and it was well worth the money. I wanted my teen and preteen especially to learn about boat safety, not just simply challenge the test. The short animated videos in each lesson make it much more interesting than simply reading the information. One frustration was that some of the quiz questions seemed to be designed to trick you when I would have preferred for them to be simply pulled from the information you were learning. One time I did have a question asked that wasn't covered until the next module and a couple times I had the exact same question twice in a row, but all of that only pertains to the quizzes and for the most part it's laid out and designed well and as interesting as it could be while still covering all of the required information. I felt very prepared for the Boater Exam.
