Since there's no video, I have to evaluate based on the book alone... but the book is not Kind at all. I can only think of it as a mere listing of knowledge that the authors possess. The description says it's "from beginner level"... Tsk~ Throw away any expectations for detailed explanations or descriptions for beginners... Why do they keep looking for cafes so persistently... If that's the case, they should focus on the cafe reservation system as the main topic and explain everything from start to finish with just that one thing... And I want to ask Inflearn: 1. Do you review courses when they're uploaded to Inflearn? 2. What are the criteria for passing the review? 3. Do you have any intention of making the criteria public? The live broadcast with the author at the very end seems like just window dressing. Gathering over 200 people and then looking at the schedule, it's just one day, about 1 hour and 30 minutes? Calling that a live broadcast is truly pathetic, and on one hand, it makes me angry... I don't know what can be accomplished in 1 hour and 30 minutes... Evaluating all these various things... including the crime of being presumptuous, I want to give it 0 points, but since there's no 0 point option, it's 1 point... I've signed up for and watched quite a few paid courses on Inflearn... this is my second 1-point rating... Inflearn, you need to reflect on this... Probably... as I expect, this post won't be visible in the course reviews for more than a few days...
