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…

verification of answers
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.

Mark course complete, filter on main page
Right now all courses on your home page are listed as "started". When a course has been completed, it should be marked as such, and the home page listing of courses should allow you to filter (or perhaps have 3 tabs) between enrolled (not started), started, and complete. Given how much space each course takes up on that home page, it would be nice to be able to separate them out.

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!

User Interface
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

Big Data Adoption
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.

Instructor Voice in Hadoop 101
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.

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

Deep Learning 101
The Review questions in Deep Learning 101 are just too hard to solve. There are too many questions which just do not refer to the materials. In module 1 - Review question 3, there is even a bug. You have 2 submissions for a yes or no question. Another example is Module 2, question 3 where the option "Experience in coding" is just not clearly enough. I still have no clue how to get the information for module 2, question 2... Since I fail if I continue (even when I understood the topic) I just don't continue on answering these…

Group the passed exams in user dashboard
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. :DThanks and keep on the good work!

R 101: Module 2, Question 3
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

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.
