I don't usually leave course reviews, but for a 3-hour course priced at 50,000 won, this quality is really unacceptable. It seems like you're teaching improvisationally without preparing a lecture script. If you were naturally good at teaching, this approach might work. However, when speech is frequently interrupted with pauses as if you're thinking mid-sentence, and when statements don't connect logically this often, I think it would be much better for students' understanding if you prepared a lecture script in advance and taught according to it. Since the content isn't well-organized, it's hard to understand what you're trying to say and difficult to stay focused. The lecture quality seems far too low for the price. Please improve this.
