I like the example-centered lectures. Above all, I liked the fact that all the lecture contents were organized well in a document. While listening, I was able to study easily by looking at the lecture documents that I had heard later. One thing I would like to be greedy about is that since they are all in one PDF, it takes a little time to look them up. ㅎㅎ It would be easier to study if you divided the lecture files by table of contents and made them into PDFs!
