Hello, Instructor Kim Young-han! I am a college student majoring in a related department. Although I learned various theories and programming languages in school, I had no idea how to apply them to web development. I was really at a loss as to what to do and how to start in a situation where I had to create a portfolio that showed clear results in order to become a backend developer. I was studying HTTP on my own and came across your lecture after searching, and I think it was a really good choice. 5 hours and 40 minutes really flew by. You explained difficult concepts clearly with examples based on real life, and you clearly pointed out the differences in confusing parts, so I was able to understand without any difficulties. It was much more valuable time than studying by searching the Internet on my own. I will diligently follow the wild course recommended in the last video and think more about what to add to my portfolio. If I spent this vacation meaningfully, it is all thanks to you, instructor! Thank you so much for the informative lecture. + Those who are wondering whether to take the lecture or not... ! Definitely take it. It's the best ^^b
