It was a refreshing way to scratch the surface of my introduction to development, which I had not even started because no one had taught me. I had wanted to start developing as a non-major a few months ago, but I just had no idea what to do. (There was no detailed explanation anywhere..) At that time, I took Tutor Kim Byeong-wook's lecture, and it was the content I really needed. I think it literally saved me 2-3 months because he explained in detail what was needed from a non-major's perspective. I definitely recommend it to those who are tired of searching for information related to 'non-major developers' on Brunch, YouTube, etc.!
