During the coding sections of the lectures, no code is provided and there's no explanation - just the instructor coding alone with fast-forwarded recording, making it impossible to follow along with the coding, and it moves too quickly to time the pauses properly. Adjusting the video speed every time is also cumbersome. The provided lecture materials are mostly just a few summary lines about the lecture, and many of these are duplicate pages. It seems like one final page would suffice, but everything that's added step-by-step as explained in the video is included as-is. When important conceptual terms are in English, the pronunciation is hard to understand, but they're not written in the lecture materials, and most of it proceeds with audio recording, making it difficult to take the course. They briefly write 4-5 lines on one PPT page, explain only verbally, and move on... I'm still early in the course, but I hope improvements can be made later on.
