This is a great starter course for data science. My learning assessment is usually how well I can teach it to someone else. I know I have a better understanding now, than I did when I started.

gives insight into the core concepts of data science but as is a crash course it does not get into the statistical or technical aspect of data science

Great overview! Passing and internalizing are different goals - take the time to read & watch not only the mandatory items but the links to Wired etc.

Good examples and notes. I have learned a lot from this course.

But it is a pitty that I can not get the grade of the test because I don't pay for it.
