Pros: 1. Low barrier to understanding the lecture: I personally read many postings and looked up many source codes, but the video was still easier to understand. 2. Good point that it provides the core: In fact, from the perspective of the student, I cannot tell that this content is the core. However, I felt that it was distinguished by the importance [Important points -> detailed], [Less important points -> simply explained]. Cons (I wrote the cons from an extremely subjective perspective.) 1. I have to keep checking the source level personally. I was curious about how the lecture is implemented and designed at the source level, although the lecture is easy and mainly explained with pictures for design and explanation. However, I remember hearing that it was a lecture on how to understand and design, although it was explained in the lecture OT. I am leaving a con in case there are students who are expecting the source level. Summary!! Overall, I think it is an easy lecture that provides the necessary content. The tuition for this course was a lot of money for me personally. However, I thought it was worth it. I hope this course review will be helpful to the instructor and future students. Thank you.
