For all of these courses, no data source has been provided 100%. All of them have an issue and can not be used for the case study. Also for the second module, even no solution has been provided in the case-study-solution notebook. To be honest, the lectures didn't provide us enough material to deal with the course and I totally learn nothing from this course. It just wastes our time.

The instructor has completely failed to create a course that works and does not adequately answer questions. There were so many errors in the week 2 data ingest notebook that even after I fixed things, there remained errors at the end that made it impossible to use and the instructor was never able to fix it (the key error since invoive_item_id doesn't exist). I learned nothing from this awful course.

Great course; would be better if the case study file was not broken (missing files, missing table in db, etc.)

Basic introduction to data ingestion pipeline.

Country table missing in lab db.The lab was failed.To Sad.

It was just waste a time.

I am totally amazed with the course content. I have never such a well structured course like this. Key take aways. are: Every Video is short and crisp, and each video is followed by transcript with hyperlinks. If one watches the video, the transcript gives view point and hyperlinks really makes you ready for the quiz which is the following section. Every problem in the course, gives exposure to various methodologies and reason for using them. Finally, the notebooks which were shared both local version and Watson version. This in turn giving you liberty to use Cloud platform to get hands on. Great content, thank you

The course is very interesting, but some of the quick questions are ambiguous and then Watson Studio part (sadly as with most IBM courses) is a chore, making it much easier to run everything locally.

everything was good explained even i didnt understand much because of my english. Thank you very much for such good course with notebooks and many related links.

Great way of getting the first-hand experience on how the data science work from the first step of getting data into the system and start working with it.

Very helpful and good course to start my journey to AI Workflow - Thanks!

I love the practical business focus of your IBM! Keep doing great stuff
