Because for some people (vegetarian/vegan) it's not different than using a "Slaves Shop" or a human trafficking business.

To kindly reconsider your grading scheme for multiple submissions
Sir /Ma'am,
I had attempted a question and got correct answer but just out of curiosity mark an incorrect choice for the same question and that further considered my latest answer as incorrect although I already marked the correct one.
Since, no attempts are left , there is no means I could revert it.
Suggestion is just to give marks not according to latest attempts but whether there is any correct within that limited number of attempts.1 vote -

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.

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 .

Big Mistake
In video "ANOVA" at 3:51 there is a big mistake in my opinion because
pvalue=1.0586193512077862e-11 not shown and the narrator said it is greater than 0.05 and this destroy the logic of the video.
Kindly fix it fast.

Advanced course paths similar to other platforms
We need more hands on experience and intermediate ad advanced level courses like coursera offers for free because it's quite expensive..! This platform is very different when compared to those because we have the proof to showcase our talents immediately after we finish our final test..! And all the courses are free..😊
