First of all, the completeness and quality of the course structure fell far short of expectations relative to the price. Since I decided to take the course after paying a significant amount, I expected practical and specific content, but overall, it felt like vague talk and my satisfaction was low. In particular, the lecture materials felt strongly like old-fashioned PPTs from 10 years ago, and there was much to be desired in terms of visual composition and overall quality. Compared to recent online courses, the completeness of the materials felt lacking. Furthermore, regarding important content, expressions like "It's hard to disclose because it's my know-how" or "It's a secret" were repeated. This gave me the impression that the core information students are most curious about was not sufficiently conveyed. As for the course content, while I understand the intent of "sharing insights," a significant portion consisted of relatively general or widely known information. From the perspective of someone expecting deep, practical insights, it was a major disappointment. Above all, the initial free lectures stimulate purchase by emphasizing the instructor's lifestyle or success stories, but in the end, it felt more like a "course seller" stating the obvious rather than actual educational content. While it might be helpful to someone, my personal satisfaction relative to the price was very low. I recommend that those considering a purchase compare and review their options thoroughly.
