Very solid course. Quick overview about almost everything you need to know at the beginning. A lot of useful links with additional material to study. Thanks a lot for sharing the knowledge, indeed!

Knowledge delivery is exceptional. Content is to the point and the tests really pinpoint the attention level of the volunteer taking the course.Thank you for designing such a knowledgeable course

Very unprofessional course. You're better off going on Youtube and watching a course of videos on the basics of Cybersecurity than this garbage. Someone with an actual good working mic, and doesn't ramble on or read off the slides is capable of teaching this better on the internet somewhere else for free than this.

AGAIN......Extremely 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.

This course is put together well. The quality should be much better, especially since there is a cost. Also customers should be clearly told that this are certificates, not certifications and there is a difference. Certificates won't help you gain employment.

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.

This 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.

sound quaility is aweful not what i would expect from a big name company like ibm. Often times i had to rewatch video and it lost my attention. audio sounds if they are recording in their basement. Terrible.

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.
