It was very difficult. The lecture is difficult to understand. I thought it would be better to explain it in a little more bullet points.

Many of the instructors were difficult to understand, and many of the quiz questions and answers didn't match what the instructors taught.

I appreaciate the content, but the structure and quality for some video (especially those presented by John F McLaughlin) is low quality.

First of all, thank you IBM for this great course. However, the video quality, sound quality, tutorial and slide can be further improved.

It was slightly difficult to follow the lessons because of the accent and mistakes in sentences by the non-English speaking facilitators

The content is good, but the audio quality is too poor, sometimes is difficult to understand especially if you are not a native speaker.

Hard to understand some instructors due to mic quality.

Extra unnecessary details that appear to act as bulk and just prolong the course.

Information is decent but the audio is absolutely horrible. Cannot believe that IBM allows such thing to be published under their brand.

Videos are old, not up to the standards of online learning in 2023. Good information but could be presented in a much quicker fashion.

this course provided a lot of information about cyber security and its history but the audio voice is not clear and needed to improve.

Відсутність адаптованого переклада українською мовою. Автоматичний переклад не передає нормально зміст. Іноді дуже важко зрозуміти.

High teaching level but at times really poor audio and video quality where you cannot read the slides or understand what it says.

I would say the content is great to start in cyber security, quality of audio and video is very lacking and requires improvement

Good introduction with key concepts. The sound is however very bad and hence it is sometime difficult to understand the speaker.

Voice quality is very poor. Content of the course was not sufficient enough to understand techncial part of the cyber security.

Audio quality isn't great and sometimes new concepts are introduced with little explanation. However, I did learn quite a bit.

The course is good but the voice are sometimes not audible and the legends have a very bad translation to Portuguese language

Sound quality really bad. Slides also in bad quality. Who uses Comic Sans? However, topics are clearly described and taught.

The audio in many of the clips was really poor and some of the slides had typos. Could do with a bit of quality assurance.

the video quality is terrible. only 480p ? and audio quality is also not good. otherwise the learning contend is the best.

The quality of the videos and audios is not good, I need to re-listen more than once and read the transcript to understand!

The volume would go in and out making it hard to hear but the transcript help me to follow what the instructor was saying.

Need a lower approach explaining terminologies and better examples. as well as appropriate feedback after passing quizzes.

The transcription of the audio was problematic. The courses need proofreading and grammar editing for clearer learning.

The audio of almost all the teachers is not clear. It's good to learn something new but it's not a professional course.
