I included a part where you write code live because it is easier to understand when I explain it live. I provided detailed explanations with code as materials and made it easy to use in a short period of time in various ways, so it is really unfortunate that you gave such a low review. I will re-record that part. It may be because the teaching style does not suit you, so I think it would be better to take a lecture from another instructor rather than mine in the future.
