Thank you, Seonhyeokjun, for completing the course and leaving such valuable ratings and feedback. My courses are designed with the motto of creating experience-centered lectures that can be applied directly in real work environments, allowing you to follow along without troubleshooting, rather than focusing on theoretical explanations. (That's why all courses are priced affordably in the 10,000-20,000 won range so you can watch them without burden) However, as you mentioned, I think some sections could be easier to understand with a bit more background explanation. Moving forward, I'll maintain the practical-focused approach while adding concepts and principles where needed to enhance completeness. Thank you once again for your valuable feedback. 🙏
