two answers showing correct answer, and other suggestions
On Q.13 of Spark overview for scala analytics, both 'group by ' and 'all of the above' is showing the answer as correct. it is supposed to be a single correct answer question. Please correct it.
second, kindly make arrangements so that there is no check-reset-check-reset-check-reset-final check loop!!
It would make more sense to save and evaluate the answer when the option is clicked.
This exam had 20 question, for each question the number of steps are :,
1.click option of choice
2.click check
3.click reset
4.click option
5.click check
6.click reset
7. click option
8.click final checkThat's 8…

Improve PA0101EN
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!

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.

Add better flow for the courses
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

improve Data Science 101 - Module 1
None of the links to the reading material actually work, I tried the links for Modules 1, 2 and 3. One of the discussion topic responses in Module 1 suggests a link to Google where a sample Chapter 6 of the book is available, but the Review Questions require answers from other Chapters, e.g. the question re Walmart is not in Chapter 6 but in Chapter 1. The selection of answers to the New York Times question do not match the actual article from April 2015 (can easily be found using Google).
Overall I'd say this course is a disappointment…1 vote -
Use a Spellchecker Before Publication
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.

Module 5 in Data Privacy Fundamentals
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?

add an autoplay feature
It might be nice to 'autoplay' a module instead of having to click for the next video. Or possibly add a next arrow at the lower right of the video?
