First of all, it's good that I can take a text analysis and natural language processing course at a very low price, but it seems like a bit of a burden for beginners like me. First of all, there is no explanation of the code used, so I have to find it separately and study it myself, and I will learn a lot in the process, but it takes too much time. Then, the overall learning pace decreases and I feel stressed.ㅜㅜ If you could give me a rough explanation of the code used, I think I could save a lot of time and learn more efficiently. Also, I felt like the overall progress of the course was not smooth.. However, if you ask questions about things you don't know, they will answer quickly and sincerely, and it seems like a cost-effective course for those who have basic knowledge of coding. I'm sorry for giving a low rating after taking the course at a low price, but I wrote it as honestly as possible. I learned a lot. Thank you.
