the overall sound quality was a bit hard to understand at some places but the information given and the way of teaching and the level of understanding all things were great.

Much of the content was already presented by the previous course (Introduction to Cybersecurity Tools & Cyber Attacks). Video quality is horrible and some slides content is unreadable even at max quality setting. It points to good resources, however, and the last weeks content was ok.

Course explanations were well written and informative. However some of the images and transcriptions were abysmal quality and a few of the quizzes actually had incorrect answers, such as the "What bit version of Windows10 can you purchase" question.

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.

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.
