Retake Exams
The point of this site is to learn and I find it ridiculous that you cannot retake a course if you fail it. That does not encourage users to learn it only teaches that you should get it right the first time or quit. I now understand what I did wrong and would like the chance to prove so and receive the badge.

BLOCKCHAIN
A learning path focused on Blockchain Technologies would be a great success. There is a huge and global interest in this set of technologies.
I finished the course "Blockchain Essentials BC0101EN" and I think that the subject is so important and deep that a full learning path will be completely justified.
Best regards.

Show/suggest learning/skill paths
Group courses to define graduation series from foundation to expert. For example, I completed a foundation or introductory course which should be a prerequisite to a more advanced course, I should know which one to take next.

Send an email alert once a course becomes available.
I would like to pre-enroll to a course that is not available yet (Text Analytics) and to get an email alert once the course becomes available. Alternatively I would also appreciate to have the option to "subscribe" to a learning path and if that learning path is updated with additional courses then I would get an email alert.
I really appreciate the Cognitive Class platform and I don't want to miss an interesting introduction to text analytics.

re-publish Hadoop 101 with a better narrator
Just a comment to say that the narrator for these courses is in a hurry, and slurs the words, and does not annunciate. It seems that the best way to review these topics is to listen once, then go back and re-read the text that is associated with the material. Also, when I try to slow down the voice, it does not seem to take to .75 .. I have to change it to .5 and then change it again to .75 .

The Data Science Foundation Path Does Not Make Sense.
The Data Science Foundation Path Does Not Make Sense. It goes from a very basic (and good) introductory course discussing what data science is and how it can be used (a 101-level course), to the next course in the path with talks about using tools that an aspiring beginner does not understand, and furthermore, it speaks in a language beginners do not understand ("Jupyter is an evolved version of Python"---??? What does this even mean? What is Python; what is any of this?)
This path is missing several steps between the first course, which is marked at having an audience…

Navigation buttons for CB0103EN set to disabled?
Buttons never get enabled despite finishing modules, hence all the they are disabled and unusable by default.
1 voteThis is actually the default behavior of the current version of the Learning Management System we are using. This works much better in a later version that we are going to be migrating to.
