I think it is ridiculously expensive compared to the content. First of all, the lectures have too much fluff. There has been no editing at all. Listening to the lectures, it seems like they just recorded an offline class and are selling it on Inflearn. As a result, it doesn't feel like only the essential information is being delivered; there is a lot of repetition and many parts that don't need explanation. The lectures feel unnecessarily long, and I feel they are poorly edited. It would have been much better if there were edits and revisions—similar to proofreading a piece of writing—and if more on-screen writing or visual aids were included. I really do not recommend this.
