Hello, Dongmin. Thank you for your good feedback. I'm sorry that the lecture content was structured in the way that I read the class materials. I think I'm not good at speaking fluently, so I put more effort into making the class materials. I think it felt like I was reading the script for each part where there were pictures and animations. Also, thank you so much for summarizing the key parts and saying that the pictures and explanations were clean. I will keep both opinions in mind. Thank you. If you have any questions, feel free to ask anytime!!
