Originally, I was listening to another Python problem-solving lecture by Professor Kim Tae-won, but it was a bit long and a bit difficult, so I bought this and listened to it first since it was my first time preparing for the coding test! I listened to all of them except Section 12, and I liked that there were many problems by type that were not too difficult for beginners to solve. I was scared of coding tests, but I was able to see that there were problems by type once, and it gave me some confidence. It's not all easy, though. There are some difficult problems, and it was good that Baekjoon problems were included in the middle. I finished listening to this today and now I have to listen to the problem-solving lecture again. The explanations are good and easy to understand. Thank you for making such a great lecture.
