I thought there would be limitations to teaching programming online, but after listening to the instructor's lecture, I could see how much the instructor had thought and created the lecture in order to overcome those limitations. Even though I'm a Python beginner, I could feel that a lot. The feedback on questions is fast, the lecture content is good, and the instructor even uploads reference materials that I can look up additionally... I think I'm really blessed to have found this lecture. I'll just trust the instructor and diligently follow the Python lecture~!!
