This course shares needed information, but it's clear where the presenter is more interested in teaching the knowledge. More often it is just reading the information on the slides rather than imparting additional knowledge except where he appears genuinely interested in the subject - there was no need to watch the videos for this reason. Some assumptions are made you know what it is he's speaking about as definitions to new concepts not spoken about in the course aren't relayed so you have to look it up and the use of Wikipedia pages as readings/sources of knowledge for the fourth course is somewhat questionable. Otherwise I'm leaving with a somewhat better understanding of the system, and where I should continue to expand on my learning. A lot of the modules also start out by saying by the end you'll be able to do things, but since the videos are all just theoretical, and the labs are simply testing commands. It gets you comfortable working in a terminal environment, but I wouldn't say it gets you comfortable enough to do a lot that has been discussed - or how to set up Docker containers for example. It relies on your curiosity to teach yourself outside of what is found in the videos and coursework. Decent information, and as a course that is self directed otherwise it's a good foundation to further learning.

Very superficial course. No practice at all. Passed this "4-week course" in one hour.

It was very general, I learned a lot

Mediocre

nice

I'm not sure how this is rated so high. Most "lessons" are 2 minute, ultra high altitude videos followed by 10-20 minutes of reading. You can get more info from random YT videos. The material is full of typos. There are very few labs and they take < 5 minutes to do because they are so simple.
