I was able to learn briefly and thickly. It was good to gradually practice in the order of practice -> inconvenience-> improvement -> practice. Rather than a long video where you have to blankly watch the instructor do it, the structure of running it right away with a pre-written script and reporting the results was very clean and simple. However, the audio volume is strong, so you have to turn it down, and because you turn it down, it's different from other sounds, so I hope it will be improved in the future. ^^ Thank you for the great lecture.
