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.

I can't be the only one suffering.

The lecture quality is not satisfactory.

The explanations centered on cases and examples make it so easy to understand. Listening to this with work experience might help me understand it better, but I wonder what it would have been like if I had taken this lecture during my undergraduate years! I learned so much, thank you Professor~

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