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.

Wish the audio was better, subtitles kind of helped but would have enjoyed this more if the audio was of better quality

must include the hands on tools and applications, many questions are predecessor asked than the actual study of it.

I think the topics are reviewed in a rush, you need to look for external information to understand some of the topics.

We should be able to see the questions we got wrong and/or there should be an explanation of why we got them wrong

it a good course information ,but I'm disappointment from video sound and video quality it too bad like 90's video

Most of the presenters in the videos were very difficult to understand and the audio quality was terrible as well.

I am giving only three stars because of sound quality. very difficult to understand because of bad sound quality.

provide good overview of all topic related to cyber security. purely a beginner course . focus more on theory .

This course has a lack of profecionality, and good structure I can review my quiz for know was I am doing wrong

Good introduction to Cybersecurity

The sound of some of the videos is very bad but most of them are good quality

some professors were a bit hard to understand and the subtitles weren´t able to properly interpret them either.

Great Content, terrible audio, and presenter accents and enthusiasm was not very good. Overall worth the effort

Course is best but the sound quality of the videos is very low. You can't watch a video more than a minute.

Good information, awesome presentation style. However very difficult to understand a few of the instructors.
