The audio is quite choppy and it is hard to muscle through the first course.

Audio quality was very poor. Though, there are subtitles. Great information

This is a great course, but some of the videos dose not have a clear voice.

Some audios are very bad. Not to much interactions. Just old presentations.

The subtitles are inaccurate and the speakers are inaudible half the time.

Some of the videos are not audible. The breaking of voice was quite often

EVERYHTING IS PERFECT ,EXCEPT THE AUDIO, THE AUDIO QUALITY IS REALLY BAD.

Audio quality is worst.

I was expecting some practical examples as well.

could've been a little more practical. The videos were not very engaging

The clarity in voice is very bad. Except that the overall course is good

The teachers were a mixed bag. Some were good while some were mediocre.

The content is good but presentation way and the audio quality is poor

it is quite basic and boring also most of the lecturers have bad audio

Cours intéressant mais qualité audio très moyenne sur certaines vidéos

Some instructors have horrible mics, other than that great course!

the audio quality was very bad. but the work and study very good

the sound on this audio is not clear, please do something to it.

Wish production of videos were as well made as the google ones.

Sound quality is bad and too many instructors to cope up with.

Information is very interesting but Audio quality is terrible.

It's hard to understand. Wish they taught it in simple way.

Good , but practical skill needed for this type of courses

Hard to understand some of the instructors but notes helps!

Much of the information is dated. Course needs a revision.

Audio quality needs to be improved in some of the videos.
