The lecture content is very basic, so I can take only the parts I need, which is good. However, since the lecture materials were not prepared, it was a bit difficult to solve errors on my own. On the contrary, I think I was able to learn how to solve errors on my own as much as possible, so I was personally satisfied. (It was less difficult for me because I was reviewing the parts I had already learned, but it might be difficult for beginners. It would be helpful if you search a lot.) I'm going to take other lectures. Thank you for the great lecture! The disappointing thing is that the lecture speed seems to be at double speed by default. It was a bit ambiguous to adjust it slowly, so I just repeated it if I missed it, stopped it, and then coded it, so it took a bit more time. It would be good if you uploaded the lecture at the default speed :)
