I'd separate the theory part and the practical part with Tableau into two separate courses. For now, I'm mostly interested into the theoretical introduction that this course offered. Doing the exam including Tableau will be hard cause I wasn't really interested as much in that. Other than that, the subtitles need to be reviewed. There are mistakes that need to be fixed and often the subtitles cover text in the video. Lastly, it would be great if there would be more notes in the resources.
