Hello. I finished this basic course and am leaving a review. First of all, I think the lecture was very practical and fun. The voice is good and the topic is well-led, so I think I fell into the magic spell. I actually have trouble concentrating, so I can't focus well, but I think I was able to maintain a good pace by breaking up the lectures appropriately, and I want to gradually increase it. I am grateful that you have explained your long-standing know-how in such a concise way, and my personal wish is that you thought about doing a design pattern lecture, so I hope you will consider a CS lecture as well^^ It's so nice to listen to lectures with Mr. Kim Young-han's voice~
