For the review questions , rather than having a 'check -reset-final check', I think it will be more intuitive and computationally more efficient to have a conditional submission. I.E In the first attempt If a check results in a correct answer, the submission should auto-lock it self. That way you will not have to reset and then again perform a final check because we have already got the answer in the first attempt.

Not a single video is working for this course "Data Science Methodology" and "Text Analytics Essentials - Case Study(For Cognizant)".

Whenever tried to open showed "File not found" message.

It will be really helpful if the voice of the instructor can be changed. The instructors speed and pronunciations was too much to understand. With only good intentions i request the administrator to make the necessary changes to help students.

When one clicks on the username, a list of enrolled courses are listed. I would suggest the team to categorize the courses as enrolled, In Progress and completed. This makes the UI more user-friendly and the user can easily keep a track of the status of his/her courses

The audio is bad enough that the transcribed text is wrong. Please make and enforce some minimum standard for recording quality, especially when it is in a course that is exclusively for an expensive IBM product! (Out of all of the course videos I have seen so far, this is easily the worst quality and presentation)

The review questions are also glitchy, it forces the user to reset the question and then resubmit the final. But in some cases, the answers have moved positions!

It would be nice to separate the completed courses from the currents in the list under the user dashboard (https://courses.bigdatauniversity.com/dashboard).
Maybe you can simply separate the list adding a new heading between the two lists. Better would be using tabs or accordion. :D

Thanks and keep on the good work!

Just want to let you know that the text next to the video is linkable, and looks it must be plain text explaining the content and context of the video.

I find when you go through the courses, it isn't easy to change to the next video. You have the arrows that sit at the bottom of the page but they don't do anything. Maybe set them up to go to the next video. Also everytime you want to go to the next video it takes a little too long for the next page to load

I am not able to access the courses.

Hi,
could you please reconsider having your files (images and pdf's) on your server -bigdatauniversity.com- instead of ibm.box.com ?

Eventually please add a pure text transcript as an alternative.

due to the company policy I have blocked any pages with file-sharing, so I can not see the images in test questions and can not view any files hosted on ibm.box.com

Both:

data.frame("student"=c("John","Mary"),"id"=c(1,2))

AND

data.frame(student=c("John","Mary"),id=c(1,2))

give the desired result

In "Data Science Methodology", there are too many grammatical errors and answer errors in the reviews and exam for me to type out.

Before a class is published online, it should have at least passed a basic spell and grammar check. It looks unprofessional.

My suggestion is:

Use a spellchecker before you upload it online. Also, at least one person should go through the reviews and exams to check if everything "looks" okay.

I wanted this course to be supplemental material for my students. But the way it is now, I cannot suggest "Data Science Methodology" to them.

I am taking knowledge on Data Science Foundational DS0101, DS0103 and DS0105. Two of its total opened accurately but DS0105 is not opening.After click on this link its again navigating to the previous page.

I don't understand what the Review Questions in Module 5: Analyzing Hacked Passwords in R had to do with the subject matter of the Module. The first question asks which programming language is best for text analytics. R isn't even an option. It makes no sense. It wasn't covered in the module. Why even ask that?
