Thank you so much for the quality class at a low price. I don't usually write reviews like this, but I decided to write a review because I hope more people will take the class! I've spent a lot of time so far, but I felt like I didn't understand it clearly and was ambiguous, but now that I've taken half of the class, I feel like I'm naturally understanding everything from the basic knowledge I already knew to the new concepts I've learned. And the instructor's voice is so good and his pronunciation is clear, so it was comfortable and nice to listen to. I usually prefer Python, but the instructor's special lecture was also very interesting. I just found out that the C language is used in more fields than I thought. If you open other lectures in the future, I'd like to listen to them all. I'd like to thank the instructor~!
