Support for more web browsers than just Chrome
I was not able to access the Lab content in the R101 course when I used FireFox. Only when I used Chrome was I able to access the lab content. This is a limitation of the Cognitive Class Labs/Data Scientist Workbench. I also noticed that Seahorse only supports Chrome. I would like to see support for more browsers, and not just Chrome.

The review question in the Demo section is incorrect
The review question posed in the Demo section is actually one of the answers. The question can be inferred from the other answers but needs to be corrected.

Size of slides in Video
Hey, thanks for the courses and videos. The slides in the videos are too small to read the details even in the full screen mode. If your intention is to educate the public, why make it so difficult for us to read the slides.

Not updated
Hello,
I'm currently doing the Hadoop 101 course. I found that the facilities for Lab is no longer accessible and the training guide for Lab is not updated. Can you guys update all the required information? Thanks.

have a way to split up current classes from completed classes.
In the my courses section, all of the current and historical classes are shown. This will become cumbersome as more are completed. To remove a completed class from the list, The "unenroll" is the only option available. It would be nice to have a way to have a "completed" section instead of them disappearing entirely so that a review of material can occur when a refresher is needed and yet stay organized.

show the correct answer and explanation why when I get a fall for a specific review question in the final check
Hi, I really like the courses provided by the BigData University. However, I find it is time-consuming to go back to find the answers from the previous modules when I got a fall in a review question. Therefore, I suggest you could automatically show a chat box after I click the FINAL CHECK, so that I will get the full explanation about why this option is correct and why that option is incorrect, no matter I pass the final check or fall. Many thanks. Hope I have present my suggestion clearly. If you have any question about my suggestion, please…

Highlight items that you are clicking on in the videos.
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.

Astonished at the choice of instructor for a core course - Hadoop 101
Hello,
I am simply astonished at the choice of instructor for such a vital course as Hadoop 101. Asma Desai's reads at rocket speed and the narration is terribly incoherent.If I have to pause the video at an important instant, before I can click the pause button, she squeezes in a dozen extra words. Now I have to move the slider to a few seconds back and re-try the pause operation.
This has contributed to an extremely annoying User experience while taking Hadoop 101.
Please replace the Hadoop 101 course video with someone who knows how to teach. I…
