Description of assignment questions is not clear. The expected answer from the questions are confusing.

The peer grading looks weird. I got a comment on my original work "seemed to be not written by me".

final project is terribly defined. Lecturers, Coursera, and Johns Hopkins should all be ashamed.

Very scattered and unfocused course. Sad to say that I learned very little from this one.

Terribly outdated, please find a more up to date course if you want to be employable

This is just because of the unclarity of the final assignment.

Terrible! Go to Data Camp and save a bunch of money!!!!

the learning way in this course was bad, to me

It is more about R rather than data science

Poor teaching! Almost a waste of time.

I don't think it's necessary lecture

lectures are too fast.dropping out.

Significantly outdated material

Poorly constracted course!
