Hello,
Everything on cognitive class has really proven to be the best of all courses to me. I have a small suggestion, most of the courses are related to data science but there is not much on natural language processing. I request you to add some courses related to the subject.
Thank you

For Integration and component Testing of a MicroService

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.

here is missing the comand

ibmcloud cr login

that is obligatory for push the image

the class page is https://courses.cognitiveclass.ai/courses/course-v1:CognitiveClass+CO0201EN+v1/courseware/754094ea513a42f39ec84d99cae78249/f1cc315d40b74e1aa6ec1cd2a3c1f985/

Divide My Courses dashboard section into :In Progress" and "Completed" sections. So that tracking is easy.

There's a link the the docker-entrypoint.sh script for the Mongo 3.4 docker container. Or rather that's what's supposed to be linked. The link is actually point to the script of Mongo 3.0, which is not on Github.

Broken Link:
https://github.com/docker-library/mongo/blob/master/3.0/docker-entrypoint.sh

Correct Link:
https://github.com/docker-library/mongo/blob/master/3.4/docker-entrypoint.sh

There's a question in the ST0101EN exam, "If the standard deviation of a variable is larger than the mean, the variable depicts:" The correct answer given is "high variance," but this is not the case. In the general case, there is no meaning to the relationship between the standard deviation and the mean (in the specific case of count data, there may be meaning...)

Dear Whom-ever-is-responsible

While I passed the map-reduce/YARN course, it would be really useful to get feedback on the answers I got wrong on the final. I understand that if there are a limited amount of potential questions, you don't want a free copy of all answer floating around the net. Unfortunately, at the moment I am unsure if I got a question incorrect because of actually not knowing the proper answer, or due to lack of clarity in the question (which was apparent for several)/misinterpretation.

Just FYI

Pronunciation in Hadoop 101 course is not clear at all. It is very difficult to understand what the presenter is saying. Also the speed is too fast. The presenter is just reading out text. The presenter should understand that the initial level of course is taken by those who don't know anything about Hadoop. The course material and presentation should have been designed keeping this in mind.

The Scala kernel isn't working, making it difficult to get some hands on experience on labs that use the Scala kernel, eg. all of the Spark labs.

Thank you

This course doesnt not have a transcript. Lectures videos are good but a powerpoint PPT or the transcripts would definitely help to refer back. Mostly Quiz questions does not come from video presentations

For example, genesis block was not discussed int the Module 3. But there is a questions on this in Quiz.

Bonjour Il serait intéressant d'avoir les certifications IT Infrastructure et Cybersecurity

The Website was down/not accessible last night, when I am in the final exam of PY0101EN, please help me to reset my final exam result.
Then I need to attend the final exam again and win the badge.
The current result only shows that only 20% result was submitted and recorded.

Does is really make sense to have an ADVANCED learning path made up of 3 INTERMEDIATE level courses.
These courses are good you should the naming consistent.

Update buttons on website , Next and prev button is not working in Intro to Data Science course.

The instructor Ms. Desai was very fast with the material presentation and a lot of her words are muffled and hard to understand. The video did not stay on slide long enough for students to view it and the next one pops up. One of the worst online class I have taken

Asma Desai has not done a good job in narrating the contents. I would suggest replacing the video for the benefit of audience
