I like Ki-seon's lecture style because it feels more like a real lecture, with scenes where he laughs and makes mistakes, rather than feeling stiff like other lectures. Even MS developers make mistakes like that, so I feel like they're not robots but people. 🤣🤣🤣 I've taken Ki-seon's lectures a lot, but this lecture is based on basic knowledge, so I don't think there's a more difficult lecture than this one (He promotes other lectures, but he reminds us of the content as a preview, so I think students can judge what's lacking by looking at the table of contents.) Since Effective Java is a translated book, it's not easy to understand, but it felt like he was translating it again, so I was able to approach it comfortably. (It's still difficult, though..) Unlike the lectures you've filmed in the past, he asks questions and answers more, so I think it gave me time to think more deeply. I really like this style!! If you didn't feel any changes until you finished it, you can get a 100% refund, so listen to it all. There's a reason Ki-seon is confident. !! p.s) When will the next part come out?
