I just watched my first video and I just wanted make a suggestion (as I am a video developer also) to be more clear as to where you are clicking with your mouse. In this case it was the menu on the left hand side, but windows were popping up and I had no idea why. You can perhaps add cursor effects or callouts to draw viewers attention. thanks.1 vote

Alternative Status Verification of Disability When Uploading Is Inherent Not Possible For A Course User To Prove His Disability
Talk to Congress, the Senate, and The President....Disability Status verification, if the user being a Veteran, is not able to provide the information, how could there be other ways to even at tempting to preserve the identity of the course taker, who has very much believe he is a Disabled Veteran? I am referring to the need of making options available in the events, if a DD214 or just a Veteran Affairs benefits letter identifying service-connection, or where there is no service-connection, and letter from the immediate doctors of the Veteran could well be upload, but the point here is that, what if the Veteran is not able to upload anything, for lack of Document Scanner which he/she could well use to produce a PDF that can be attached to an email and sent to Cognitive or use to facilitate the upload by means of web form feature on the Cognitive Class web page that allows you to. So I am saying, well that I am Veteran, and I have a letter, but if I am not able to upload it in anyway, because of lack of Document Scanner how can I be given the opportunity to find a remedy to that? Thank you.

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. ).

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.3 votes
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.2 votes
