The sound echoes a lot, the GitHub address shown as course material isn't provided accurately, and there are quite severe jumps in the lecture content for a beginner level, making it difficult to follow comfortably. I don't understand why the rating is so high.

The lecture quality is not satisfactory.

This is a great lecture for non-majors to learn OS.

Thank you for the instructor's passionate lecture. Thank you for covering a variety of topics.

Although it is theory-centered and not very deep, I liked that it covered topics that I had not thought of, unlike what I learn in my major.
