The course was very good with repetition and review of key concepts that allow absorption. I would like to see a review of incorrect questions after each module test in order to reinforce areas of weakness (wrong answers). I recommend printing key sections such as sound signals, navigation lights, etc. Printable charts would be helpful for the boating flags and signs sections as well. Everyone should buy the handbook as an ongoing reference. One should make notes as they go through the sections as reference will be required to write the section tests and learn the information so that boaters remember important things while on the water.
