This is an honest review of the course. First, the lectures are not friendly compared to the paid amount. I bought it after seeing the name value, but I regret it. Please consider this and buy it. Second, the table of contents is divided, but the lectures are not divided in the source. Since the lectures are all in the same file, if you follow the table of contents, the sources of the lectures you have previously done will disappear. You have to organize the sources yourself.
