The lecture was really good. It was the most satisfying lecture among the online lectures I have ever taken. Since it was my first time studying this field, the terminology was difficult, but the lecturer only focused on the key points and explained them in an easy-to-understand manner, so I was able to finish the lecture without getting tired. It was also very helpful that he pointed out what difficulties I would encounter in actual work, what traps I should avoid, and what I should think about more. After listening to the last lecture, I think that he is a person with a great mind as well as teaching ability. I will listen to it a few more times and study it. I highly recommend it!!
