I'm watching it well^^ I watched about half of it, but it was good because I was able to take the class to vaguely grasp the concepts of things I used in practice, learn the terms, and learn things I vaguely knew accurately. There are many reviews saying that the speech is fast, but I personally listen to other lectures at 1.25x speed, so it was suitable for me because I could watch without adjusting the speed. The instructor lectured as if he was skimming through the entire material, so I think the speed and short lecture length actually helped. However, I think it would be better for majors like me to listen to it rather than beginners.
