Sorry but I found the on-line narrator dull and uninteresting. The delivery of the content did not keep me engaged. I purchased a boat smart study guide at Can Tire that had a copyright date of 2020. I reviewed the book and did the quiz at the end of each chapter. I also did the practice exam. I was surprised to find that I had to go through the entire course again on-line before I could write the final exam. I also found a number of questions asked where the answers available did not match what was taught. Still glad that I did the course and have the book for reference.
