I think I would be able to understand better if time were given to practice alongside the lesson. The content is great.

Thank you, I'm enjoying it very much

I suddenly found myself preparing for the civil service exam, and since I'm weak at memorization, I was initially studying inefficiently by focusing on problem-solving. Then I started organizing concepts with Python and the content began to be understood much more intuitively, especially difficult concepts like the characteristics of stream ciphers became easy to memorize once I coded them directly. I really want to recommend this to those who, like me, switched from development to civil service exams. I'm truly grateful that I can listen to such beneficial lectures for free. This was the lecture that helped me the most while preparing for the civil service exam.

Thank you for the great lecture!

I chose the very first lecture, but I don't understand it. It's unfamiliar and looks like alien language, but the whole course is shown only in pictures, so I don't understand anything. I think it would be better to show the first course, which starts with print? and other output values, in video so that beginners can watch and follow along. I gave up after watching it.
