Okay. I'm taking this class to organize the content after studying on my own and get help with parts I don't understand. Above all, even though the videos are short, the instructor explains things in an easy-to-understand way with examples, which makes it easier to understand! Even in the case of mini-projects in between, I can organize them using only the content I've learned, which helps me think! The lectures are free-spirited, so I liked that they weren't stiff! It was also really helpful that the instructor spoke in English instead of translating the terms into Korean! For those who don't know at all, I think it would be fun to watch this lecture while using the textbook you have! Fighting!
