The lecture is generally close to simply reading the book content aloud. Personally, I think the advantage of video lectures is not just simple content delivery, but also including supplementary explanations about why each concept works this way, which helps with understanding. However, this lecture was somewhat lacking in this aspect, making it not much different from having to Google when you don't understand something while reading a book. Also, if tips that could be helpful in practice, such as shortcuts, were reinforced, it would make for a more beneficial lecture. And the class materials are not updated, so you have to find and correct them one by one. This is really too much.
