This course provides an introduction of some important concepts and tools on a very important aspect of data science: cleaning and organizing data before any analysis. A must for any data scientist.
This course is really a challenging and compulsory for any one who wants to be a data scientist or working in any sort of data. It teaches you how to make very palatable data-set fro ma messy data.

all the practical things had to be learned by self learning instead of in the course. Peer graded assignment took for ever to pass

The worst! I don't recommend you to take any course from this institute. It is just wasting time and money.

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

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