poorly explained. Exam answers when answered, sometimes it gives you true answer and sometimes wrong answer even though i gave the right answer.

The course materials need updating. The IBM platform has changed which has made it hard to maneuver the website and follow the directions given.

This needs to be revised. Its very confusing, you need more assignments between lessons so that we can show we understand what we have learned

This course can have an easy example to explain the methodology for Data Science but there are hard ones and I really don't like it that much.

The case study was too difficult to understand. I wish a more easier case study was picked to elaborate the datascience methodologies on it

Maybe of interest to people who have no clue about any sort of methodology or problem solving. Too boring and repetitive for everyone else.

Not good for beginners, the CHF example was complex and I think this course should be updated with better examples and explanations.

I feel this course is not up to mark. More reading materials should be provided. It will help learner to understand the concept.

Terrible. Very basic. The tool tasks didn't work- timed out. Has no one to grade when it was over. I hope these get better.

I felt that the course was ill prepared. Also I did not like the explanation using the food example. It was not clear

I would have liked for the course to go more in depth of the statistical tools. It was confusing and hard to get.

The case study should have been a general case bit specific to health its difficult to get around the course.

This is the 3rd introductory course in this professional certificate. I am yet to learn something useful.

Examples are not clear. wasnt able to understand the methodology so well. Please use lay man examples.

The methodology could be more explained, with different examples and the steps could be better explored.

The case study in the video is quite boring and it was very time consuming to understand the it.

Very high level in most parts and in some is to detailed without any noticeable reason.. (IMO)

It's incredible how many writing mistakes there are on both the presentations and the quizes

need a very huge improvement with regards to customer support and query resolution time

Too confusing. The separation between the sections are not explained in a good way

Not very useful. You don't gain any practical skills after completing this course.

The case study used in this course is really difficult to understand and follow.

Not enough examples and the videos were running fast and not really explicative

Very dull course, didn't learn very much and the assignments are very tedious.

video clips of IBM Watson interface need up to date with its current version
