A good course. I got to learn many new & informative things. But the video sound quality is too poor. The voices are muffled and you can't hear properly. Only a few videos are clear. You have to live on subtitles in order to understand what the instructors are saying.

Good to learn. Have many loopholes on the level of beginners as need more reading about every video. Although the candidate could not get more clear. Candidate clears the quiz but not too confident about the knowledge. Thank You

All chapters are of poor technical quality. Especial the audio quality in close to inaceptable. Some chapters are also of badly presented content. Only two are at least informative. Some refernces are not technically not usable

It is a mix of webinars that have been cut and poorly edited to create a course. There is a part showing an IBM tool in a pre sales way instead of teaching the concepts.
