After work, I was tired, but I wanted to try it little by little, so I walked along a path I had never walked before. Although the quality is lacking, I am very proud that I completed it. I received a certificate after making my 4th project, which may not be much to some, but it was very rewarding to me. It was really great that he didn't just reply and finish, but also analyzed my project, recommended good sites to refer to, and suggested directions for me to take the next step. There are a lot of good contents on YouTube, so I think it would be good to subscribe. Also, the lectures are not about teaching you all the functions that you don't use often, but rather about teaching you essential concepts, frequently used functions, search skills, and other necessary things in detail, which makes it interesting. If it had been rigid, I don't think I would have been this interested. I think it would be good for people like me who are not majors or have no basic knowledge to listen to it.
