It was the best course. There was also a Q&A section for each chapter, and the answers to those who asked questions were accurate, and they also provided advice on knowledge outside the course. I am Japanese. I don't know English. I'm talking with a translation app. The subtitles on the video helped. There were some parts of the request where the display disappeared quickly, making it difficult to understand. However, I was able to complete the robots. I'll be reviewing it many times from now on. Because I'm sad to see it end. Thank you, I'm satisfied.
