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.

The lessons are good, but they do not prepare you for the tests or end-of-course project.

Topics were OK but the focus on R and no other tools is frustrating
