Hello. I took Ttaebae-ssi++ after Ttaebae-ssi. I majored in numerical analysis, but I was mainly a program user, and now I work as a program developer. I took Ttaebae-ssi++ because I use C++ in my work, and while reviewing the entire object-oriented part of C++, I watched the teacher's videos on YouTube and after watching the computer operation principle, I took Ttaebae-ssi. I started programming with this lecture, and I think I made the right decision. I thought Ttaebae-ssi++ was a lecture that was really well-made, but I thought Ttaebae-ssi was even better. Specifically, I felt that it was more convenient for the students and explained the content in more detail. Well, I read other reviews, and there were many replies that did not trust me if I only listed the advantages. As I wrote before, I started with this lecture, so I cannot compare it with other lectures, but since it is an online lecture, some people may think that the lecture time is a disadvantage. However, as a beginner, I was very satisfied because I thought that it went over everything in detail. I started last year and completed both lectures, but it's not like I'm directly solving something in the field. However, as I read the code, I thought, "Isn't this something that was talked about in the lecture?" and I searched for the content on Google or the lecture list. As I followed the title of this lecture, I think I've accumulated a little bit. I learned a lot through this lecture, and I feel good already thinking that I'll make more of the content my own as I review it. Thank you for the great lecture. p.s. I'm also watching the graphics lectures on YouTube. Although it's different from my major, the content is interesting, so I'm looking forward to the next lecture.
