The lesson content was smoothly delivered so that I can appreciate that. Thank you. However, this time I was unable to use the microphone set for the first time, and I don't know the reason. It was difficult to hear in terms of audio, which affected the class. The breath from the teacher's microphone interferes with listening. Keeping the microphone a little further from the mouth would be better. I think a pre-check of both the lesson content and the system's functionality is necessary.
