I've gone through each iteration of the fast.ai courses and must say that it is worth it every time. The latest 2019 courses are again excellent. Even though I've covered the concepts before, I always learn a ton from every lesson. Although it is recommended to dedicate ~10 hours per lesson, it is very possible to go through each video, then circle back to focus on one of the concepts/problems presented. I recommend giving the first lesson a try. It is very rewarding feeling like you can actually do or build something at the end of each lesson.
