This is a difficult lecture for non-majors. Most of the written exams are taken without studying programming languages in depth, so if you just watch the lecture videos like this, you won't know which parts to take notes on... It's also difficult to review without a textbook. Also, since only the lecture content is shown in the video, it feels a bit distracting. They draw a lot of underlines and arrows, but the excessive animation effects are quite tiring. I think I'll have to watch the entire lecture quickly once and then watch it again to follow along. The curriculum flow isn't drawn as a whole, and the previous and next lectures aren't well connected. They say there are no separate printouts for the example problems, but it would be nice if you could print out the key contents of the lecture screen so that you can review them. Whether you're studying on your own or through other lectures, it would be good for organizing in a short period of time if you watch it while studying for practical skills. In summary, This is a good lecture for those who have been exposed to programming languages through notes or other lectures to learn in a short period of time. This is a difficult lecture for non-majors who haven't been exposed to the meaning of functions and variables. + This is a review after listening to the lectures up to the past questions. I recommend this as a final lecture to those who have taken other information processing practical lectures. It is too difficult to prepare for the practical exam with just this lecture. Since it is a lecture where you can only see the board online, it is difficult to follow the flow of the solution because the board is written in every blank space on the screen. I also have no idea how to solve the code in the exam room. If you say, “If you just look at it, it will show the divisor and the sum, right?”, beginners will have no idea at all because they have not encountered many problems. I think it would be better to listen to other books or lectures at least once and finish with this lecture. If you listen to other instructors’ videos and Inflearn preview videos on the same topic on YouTube, you will be able to know which introductory lecture is better. It is true that I lack study. That is why I listen to the lecture, the introductory lecture. As a non-major but a student who is preparing to acquire it for related work, I wanted to share my review with a small number of students who are similar to me.
