Very Poor audio and screen shots. All hazey. Bad content for learning or even for simply viewing.

Very bad pronunciation of instructors, snapshot were very blurry. voice quality is poor.

i can not see my completed certificate here but asking again and again my id check

Content is good, but the audio sucks and there several wrong anwers in the tests.

Poor audio quality was too disctracting. Unenrolled from course.

some material was hard to interpetate and was out dated

videos are low quality and audio difficult to hear

In Certificate IBM logo is not available.

The audio is not sound and clear enough.

Audio in some videos are garbage

Audio is hard to hear at times.

Video quality is way too low

Death by powerpoint.

very useful

to complex

most of the lectureres are very difficult to understand so I had to read insted of listening to them. For the subject I didn't know at all, the explanations were very unclear and difficult to understand.

my most challenge is to understand what they are saying. In the intro video it was perfect but the actual lecturers are very difficult to understand. As it is a new subject for me it makes the difficulty triple.

as I have already started the course I will finish it but expected much more from IBM.

these people might be geniuses in what they do, but as in the case of teaching something in English, I find them not that good.

AGAIN......Extremely poor quality video and audio. Very surpised at IBM for delivering such poor qaulity content and also dissapointed in Coursera allowing such poor quality content. I will would not recommened this course. Save your money and hard earned cash.

This course is horribly boring. It feels like it was created in the 1980s. There is no entertainment value and the audio is terrible. I can barely understand the presenter and I'm just looking at some slides.

sound quaility is aweful not what i would expect from a big name company like ibm. Often times i had to rewatch video and it lost my attention. audio sounds if they are recording in their basement. Terrible.

good course. my problem is coursera is scuffed and i did not receive my badge for this. i've tried redoing the course and nothing. fucking scammers trying to squeeze another month out of people.

Terrible. Can't understand speakers. Even the written translations have "inaudible" for certain areas. Are you kidding?

It was one of the worst course ever literally disappointed by IBM course designing team... IT CAN BE BETTER !!!!

I took the course for free and now it requires payment for a certificate why...........

all work done and when need desktop to complete exam, need to subscribe

Worst course ever on coursera. Highly unprofessional and unpractical.
