I've already taken one basic crawling class and am taking three more. I really liked how you really think about your students throughout the lecture. And it's really fun how you sometimes make small mistakes and deal with them flexibly. For example, when you can't remember English, you look it up and you go, "Oh my." What changed after taking the lecture is that I actively write code and get the results I want. This is thanks to the instructor who really organized the lectures well. Also, it seems like you have a magical power that makes you continue to develop yourself to advance without being satisfied with your existing skills. It seems like a great happiness that you can take a class like this for less than 100,000 won. What I want to say to the instructor 1. I would like to have a class that focuses on Coupang. (This is my personal opinion since Coupang is a powerhouse online._) 2. I would like to have an advanced class that goes beyond the beginner and intermediate levels. (Of course, you may be making a class. ㅎ) 3. I am curious about data-related languages and how people who actually handle data work. Also, if there are any classes on this topic, please let me know. ㅎ
