I think it's a good lecture, but there are many shortcomings. First, there's the volume issue. I've never turned my computer speakers to max, but this lecture was the first time I turned the speaker volume button to max. The sound was still low. It's a paid lecture, so it's a bit disappointing that they didn't pay attention to the volume. Also, when I actually import and run the files provided as lecture materials, red lines appear on all the codes and they don't run. I tried writing them down myself, but... It would be good if they explained things like connection pools in more detail, but it seems like they're explaining them briefly to save class time... I feel like I'm disappointed.
