My thoughts after listening to the lecture 1. The lineup is suitable for beginners. Rather than digging into one thing and explaining everything, it feels like the overall flow is explained. 2. The instructor explains based on a pre-recorded video, but the recording goes by very quickly and the instructor's explanation is slow, so it is out of sync and difficult to understand. 3. The recording playback length and the mouse pointer are shown twice, making it difficult to focus and uncomfortable to watch. Overall: I wish you would explain slowly yourself rather than based on a pre-recorded video! I look forward to good lectures in the future.
