Some of the material overlaps with the previous course. Videos can be a bit rambling, and quizzes could be improved by using clarifying language and de-emphasizing trivia questions. The material on Linux and Windows is a good intro to how the operating systems, but not especially meaty on security measures. The cloud modules suffer from the same -- they introduce basic concepts but do not cover what you can do to secure VMs. OSX doesn't even get a video. Most useful in terms of getting the hang of manager-level language about security.

Goes over relatively basic information. Seems to repeat itself from other courses and uses the same videos. Visual quality of the recordings are questionable at times and not legible. Tries to cover in-depth information, but then will side step for a half hour to teach you about commonly known keyboard shortcuts.

Most of the quizzes have questions which are unclear and doubtful .

Few questions are out of the course material which are very confusing and no proper details related to questions are available on the internet as well.

The questions aren't reviewed properly with no system to check on the wrong answered questions

Not gonna lie, this course is really boring. Most of the time you will be asked to remember corporate lingo and week 4 sounds like a commercial for IBM's cloud services.The only redeeming part is week 3, which is a decent intro to operating systems. (But they're not kidding when they say "basics")

Good information, I enjoyed the course, but really does not provide as much information as the title would suggest. "Operating System Security" didn't really dive much into Windows or Linux, but just gave a very basic overview of the operating systems themselves.

Some of the video presentations lacked quality of video, and the data displayed were blurred and illegible. Did not expect that from courses being offered from an esteemed organisation like IBM

I thought there was more practical course. and because I already knew most of things, but I didn't have any courses in cybersecurity. So it's more like to high school students dedicated.

Content is great but a lot of the graphics were unreadable due to color combinations, size, or being out of focus. Sometimes they even covered up useful text on the slides.

While the information was good, may of the images used in the video lectures were blurred, so I had to use other resources to get through the quiz questions.

Terrible quality slides, unreadable screenshots in most cases. Repeat videos and sections from the first course in the IBM Professional Cert.

the videos were very not-interesting. and there was problem with sound. also something wrong with the quizes. but content was good.

The material from course 1 was repeated a lot, some bad audio and visuals here and there. Operating systems week was useful.

Way too general, do not really understand the need for the OS week, just talking about shortcuts of the OS

Not that great experience . I have taken other courses which provide better explanation then this one.

Some instructors don't sound properly and the slides are also not clearly visible despite 720p.

Interesting and usefull content, although the "live chat" audio must be done something about...

Fairly general, not too much focus on security

Some reference links need to be updated

The closed caption did not match what the speaker was clearly saying.

Pictures,screenshots and charts used in the course are not clear

The quality and sound of the videos could be better.
