The material was insightful, and I especially liked the lessons on anti-fragility. I also liked the concepts on protecting teams: People, Process, Product. My only issue with the course is that I felt that quiz and test questions were not geared toward testing/reviewing my knowledge of course materials, but rather at seeing how confusing the questions could be constructed. I know it's important to make the tests challenging, but I felt like I was watching more for tricky-worded questions that I was at looking for answers.
Also, I kind of wish the final exam would be an all-or-nothing event like it was with the first two courses. While it's nice to get unlimited tries at the questions, I feel it lessens the overall value of the certificate, knowing that anyone could pay the money and force their way through to a passing grade, simply by guessing enough times. I sort of feel like I paid for a participation trophy.
