I have given this course but the mentor for CIA was not that much impressive for knowledge sharing. His voice seems he was already tired before session in short no energy in delivering the knowledge.

Course content can be re-organized better to be more clear. Conent is also not most up-to-date. Slides images are blurry and difficult to read. Caption text has many errors.

Audio was garbled and slides were blurry. Thanks for choosing subject matter experts but it is not relevant if I can barely hear or see what they have to say.

The content is good, but the video quality is terrible. I can't read the slides even at 720p. Also the voice breaks up and the subtitles don't do justice.

Quality on the slides are really bad quality and at times blurry. The instructors are difficult to understand also really bad audio quality.

The audio and video quality are very bad and the content is also very weak. It's not what I expected from the course, especially from IBM.

Very theoretical. Did learn underlying structures for data security. Would have preferred teaching of hard skills using any platform.

Too much management speak. Wished it would have gotten into the subject and techniques of cybersecurity quicker. Lost interest.

Very Poor audio and screen shots. All hazey. Bad content for learning or even for simply viewing.

Content is good, but the audio sucks and there several wrong anwers in the tests.

Poor audio quality was too disctracting. Unenrolled from course.

s​ome material was hard to interpetate and was out dated

In Certificate IBM logo is not available.

Audio is hard to hear at times.

V​ideo quality is way too low

very useful

I do not recommend this course unless you are starting with 0 knowledge of computers and security, and even then, you can probably do better.

TL;DR - Very poor audio/video quality, inconsistent/incorrect information in several places, and a truly bizarre mix of ELI5 and unnecessarily in-depth information (even within the same videos).

The first half of the course is all about business process (ex. ITIL) and then rehashing the CIA triad and AAA (which was already covered in the preceding course in the specialization). This part is ok, though the business process piece felt out of place and disconnected.

The second half is the idiot's overview of operating systems mixed with some randomly in-depth information about file system formats and kernels. Ex. there's a video that explains what a file is (idiot's overview) and then goes into NTFS and FAT32 (randomly in-depth). If I don't know what 'file' and 'folder' mean, I sure as heck won't be able to figure out what file system format is suitable for a single-partition 128 GB drive!

The worst parts, though, are the poor audio/video quality and the inaccurate/conflicting information and quizzes. Many of the slides in the videos are so pixellated that they're completely illegible. There is missing, incomplete, or contradictory information. And, some of the information has become outdated, so even if it was accurate at the time, it's wrong now.

Really very disappointing. Let's talk about form and substance. For the form, we have the same big problems as in the introductory training: we hear badly, so automatic subtitles contain a lot of errors. What is new is that some slides are blurry and partially unreadable. Regarding the substance, we do not learn anything really interesting about cybersecurity. There are even videos on Windows keyboard shortcuts! As in the introduction, most of the speakers are not teachers. They get to confuse you on subjects that you know very well! Much talk is very vague, commercial, or only advertises IBM products. The tests simply repeat the content of the slides, often without understanding them.

most of the lectureres are very difficult to understand so I had to read insted of listening to them. For the subject I didn't know at all, the explanations were very unclear and difficult to understand.

my most challenge is to understand what they are saying. In the intro video it was perfect but the actual lecturers are very difficult to understand. As it is a new subject for me it makes the difficulty triple.

as I have already started the course I will finish it but expected much more from IBM.

these people might be geniuses in what they do, but as in the case of teaching something in English, I find them not that good.

A​GAIN......E​xtremely poor quality video and audio. Very surpised at IBM for delivering such poor qaulity content and also dissapointed in Coursera allowing such poor quality content. I will would not recommened this course. Save your money and hard earned cash.

I​ continued with the second course in hopes that the quality might improve. I was naive. The course material is repetative. The course sound quality has not improved. The same instructors with horrible sound quality were used for this course as well.

T​his course is horribly boring. It feels like it was created in the 1980s. There is no entertainment value and the audio is terrible. I can barely understand the presenter and I'm just looking at some slides.

First week is mostly repetition of the previous course, then most of the other contents are only about bullshit terms, while the very few real content was on a very basic level.

Terrible. Can't understand speakers. Even the written translations have "inaudible" for certain areas. Are you kidding?

It was one of the worst course ever literally disappointed by IBM course designing team... IT CAN BE BETTER !!!!
