The course materials presented was great. However, the audio was poor at times and the text didn't have the correct content when the audio was inaudible.

Good quality content but audio quality during most of the course is not good. Some places the audio and video didn't match even CC and text did not help.

The materials are excellent and the organization is pretty good but some of the speakers really need to review the material before they start presenting.

At times, found the videos difficult to ear. Didn't always understand what was being said. The practice quizzes helped significantly with understanding.

Somewhat disappointed. The poor audio quality and dated materials make for a less than enjoyable learning experience. The course should be updated ASAP.

Quality of videos is average, audio is very bad in several videos and the english pronunciation can be inaudible at times from some of the presenters.

No practical implementation of any of the tools has been given. Theoretically this is the best course with all the information required for beginners.

Audio is bad - garbled and low

Accents hard to understand

Some slides fuzzy

Parts seem dated

Can't really comment on content - just learning the subject

Course content is too good, but I find hard to understand because lecture's audio quality are too bad as I had to refer most of time on transcripts.

I love the course and the teacher teaching methods. But there's a little bit hardness for me to understand the teacher voice because it's not clear

Content was great, however the audio was very difficult to hear and understand. The speakers should use professional microphones and speak clearly.

Material was out of date, audio quality was bad, and some instructors could barely speak English. I've taken much higher quality classes on Udemy.

Informative, but many of the presenters have poor audio quality and heavy accents which make for a difficult time understanding the information.

I was expecting to learn some practical explanation on cybersecurity but couldn't find any which made the whole process of theory quite boring:)

Good introduction to cybersecurity. However, there were many errors in the corresponding text and several lectures are very hard to understand.

Very informative, but the audio quality on some of the videos is poor. Also I think the reading materials provided should relate to the tests.

Presenting the content needs to be improved in an interactive way. Sounds are not good to hear. Content needs to be more clear to understand

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.
