Hello,
I am simply astonished at the choice of instructor for such a vital course as Hadoop 101. I implore you to change it's content, specially the narration and to check the some labs if they can be done or not

Where is my certificate I scored 100% but my certificate is not received

I am using Firefox on Windows. There is a glitch with your player. Whenever, you click the 1.0x speed button, the speed doesn't change. That means when you change the speed you can't return to 1.0x speed.

I think it will be a great idea to have a separate "My Courses" tab on the menu, or profile pull down menu. Because, it's confusing and unease for us to find our link to enrolled classes. It also great idea to separate the menu in the My Courses tab menu with In Progress and Completed

Data Science Methodology > Module 4 review question #2
You didn't list the answer anywhere I could find in the material provided. Yes, I googled the answer (and hastily marked the wrong one), but is that the point?

Hello,

I see currently there is no way to re-attempt faild courses. it would be great if you add re-attempt like after 1 week or month. Maybe with different questions if possible.

Thank you.

Best Regards

There must be a check in the system so that empty answers are not submitted by the users by mistake that will cost their grades and lower their marks and reduce their chances to pass the course with flying colors.

I found that the questions included in the module 3 are not in accordance with it.
Found that these questions are not covered by what's discussed in the module.
No sure if this is designed purposely.
They resemble more to the topics covered in the module 4

How can i retake the course?

Thanks

When in the "My Courses" area, it is very hard to tell which courses are completed and which are not unless you go into each one and check the area that has certificates and badges.

The easy way to fix this is once a certificate or badge has been issued, mark the are that says "Started - Any Time, Self-Paced" with "Completed" or "Passed" or "Failed".

The ability to remove completed courses or put them in a separate tab would also be nice.

Contact users to fix issues

Make all lab notebooks available under "My Data" so that I can come back and refer to them easily once all of the classes are done.

Matrix multiplication in numpy is performed with A.dot(B)

np.dot(A, B) returns the dot product

I had no way of showing my gratitude for the wonderful course on your site that's why I am posting it here. I took your course DA0101EN and am immensely grateful to you.

Thanks and Regards

There should be an option to retake the exam . Questions can be changed if we take the exam the second time .
