1. Although I've only listened to about 1/3 so far, I feel that writing classes is slowly becoming ingrained. For those who are only familiar with the concept of classes in their heads but whose hands can't follow, I think this is a lecture where they can feel significant improvement in their skills. 2. Through writing Classes, the content learned from Level1 to Level3 is naturally reviewed. You can see traces of the instructor's consideration for not just individual lectures, but also for how multiple lectures are naturally linked to create a synergy effect. If you intend to study artificial intelligence, I am confident that Gongdaehyeong-a's lectures can be the best choice. (I was going to progress further and then write a review, but I wanted to try being first, so I'm posting this. ^^ )
