The course is structured in modules. With limited time available to dedicate to the course, this was very beneficial to me. The quizzes at the end of each module reinforced the learning for that module. My interest in completing the course was definitely peaked by the encouraging screen and email messages congratulating me on finishing the module and encouraging me to continue on to the quiz. I didn't always have the time or inclination to continue but was influenced to do so based on the feedback. I also liked knowing how much of the coursework I had completed. It allowed me to manage my time. I also liked knowing that I could have multiple opportunities to write the final. I am now boat smart. Thanks Boatsmart!
