This is CS knowledge that I always tell myself I should study. Actually, the content itself is difficult for me and doesn't sink in well, but thanks to the instructor's materials and explanations, I can properly grasp the necessary concepts and flow. The short lecture time makes it easy to review, which is great. Even just collecting CS knowledge amounts to quite a bit and seemed daunting, but it's so good that you've selected only the necessary parts and taught them like this. Thank you.
