1. You have to take into account that he is not a professional instructor. 2. It would be better to separate the Git part and make a separate lecture, and only include the Vue and Firebase parts in the lecture. Or it would be better to include them as an appendix at the end of the lecture. 3. I was confused and had a hard time because there were too many skips and omitted lectures when I first listened to it, but it was very helpful when I studied more and listened to it again while organizing it. 4. Despite that, I think the instructor's passion and quick feedback are worth the money. 5. I think the next follow-up lecture will be more polished and a good lecture. I look forward to the next lecture.
