organize the learning paths in a better way
After completing the Introduction to Big Data course, I realized that I can't find a page that displays your overall progress. (completed courses, badges, grade, etc. ). I suggest you add a page where the completed courses are displayed, as well as in progress courses. Thank you for your understanding

Python 101 - Course issue
At Module 2, on the Dictionaries II in Python chapter:
After minute 2:53 of the video, audio and images do not correspond anymore.PS: another idea would be the implementation of a issue report tool. (I did not found the proper place to do so).

Basic??? 101??? Is it a joke?
For a course entitled Scala 101, this course is pretty advanced, designed for those already familiar with enviroment, vocabulary and broad programing experience. I gave it a shot but I felt like it was a desastrous waist of my time. I strongly suggest you go back to scratching board and redesign it for people with no program experience, or do not classify it as "basic" or call it " 101". Those of us really interested in learn it would really appreciate that.

Correction in video of 'Data Frames' in Module 2 of course R101

[<-.factor(*tmp*, ri, value = "Dr. StrangeLove") : invalid factor level, NA generated) and adds a row like this to the data frame( <NA> 1964 94)The command should be as below, which is correctly mentioned in the lab:

Whatever is used to spellcheck the transcripts must not recognize the word "bitcoin". In the transcript for Bitcoin 101, there are references to "big corn" and "big Korean network".

Choosing Between R and Python to earn the Data Science Foundations – Level 2 badge
for earning the Data Science Foundations – Level 2 badge,
Why is it mandatory that I have to take the (R 101) course and not the (Python 101) course?
I mean we should have the choice to take one of the programming languages and not to be forced for the R language only.Thanks in Advance.

Python 101 in Data Science Fundamentals Learning Path
Learning Path : Data Science in Python
I noticed you have a Data Science Learning Path: Data Science Fundamentals but the programming language to complete that path is R (R 101). What if there is another option to customize the Data Science Learning path with another programming language such as Python.5 votes -
Course Completion Certificate linked to Linkedin profile
Course Completion Certificate linked to Linkedin profile
It would be better to post/link the Course Completion Certificate and/or Badges to the Linkedin profile. I think it would also advertise the Cognitive Class at the same time giving the user more credentials in the data science Field19 votes -
Make the course interactive
The course is too passive for the learner. I don't have to do anything other than answer quiz questions. Even the labs have all the answers typed out. Is this intentional?

Is there a way to access courses from the old Big Data University?
There is a specific course that I have found that I want to take, but it is in the archived courses from the old Big Data University, and it says that I cannot create a new account to sign up for it. How can I access the course?

Add a course completion indicator in course overview
Currently, it seems impossible to check progress or completion for a course from the completion page. This is tedious, especially for people with distributed time slots and lots of open courses.

add progress status for "Learning Paths"
Love the courses and site but it would be really nice if the "Learning Paths" and "Courses" pages showed some type of progress status (ie: completed courses).

Graded Review Questions are not related to the Module
Hi,
Just finished Graded Review Questions of Python 101 / Module 2 - Python Data Structures I.
Found that these questions are not covered by what's discussed in the module.
No sure if this is designed purposely.In my personal opinion, it would be good that those questions are related and can be used as a review of what's learnt.
Thanks and regards,

dynamics and modulation
My general observation is on the voice overs reading the script., It sounds too mechanical, a subject matter expert when teaching will modulate concepts better, in a way students can remember by remembering their voice or dynamics. The voice that is reading the transcripts lacks dynamics and the human element. Its too mechanical. Can be improved for better.
