I took the course on the bus home yesterday and am writing a course review. I chose this course after much thought and careful consideration, and even now, I think it was a really good decision. For reference, I am a non-major who has absolutely nothing to do with computers. It took me 84 days to take the course, but in fact, I had an accident and had surgery on my eye, so if you exclude the period when I couldn't attend at all, it took me about a month. (Please keep in mind that I can only attend the course after 5 PM on weekdays.) This course is very helpful in establishing solid concepts. If you follow along step by step, you can see yourself growing in no time. It also clearly explains topics that I had vaguely known or didn't know exactly, so there were many times when I thought, "Oh, that's it?" Of course, it might be difficult for a non-major to understand everything, but the course explains it logically enough that there are few such instances. Especially when you explained about memory, it was so detailed and accurate that I was happy. (It was so...difficult because of this part..) I plan to watch this lecture 1-2 more times in the future. I think you can easily learn the intermediate level of C language with just this one. And if you have time, I think it would be good to listen to Professor Hong Jeong-mo's live special lecture. It helps me draw my dream about what I will do and motivates me. I had a hard time because I fell behind a lot due to an accident, but thanks to you, I was able to fill in a lot of my shortcomings and receive a lot of help. I am really grateful, and I will take other lectures with you in the future.
