Pros:
* Simple and intuitive interface
* Many illustrations and diagrams, so the material is easy to learn.
* The course starts from simple to complex, so it's easy to complete even if you are fluent in English
Cons: You can pay at a discount only one year in advance, but I'm not rich.
Overall its a good and fascinating course that will allow you to study Data Science even if you are not very fluent in English like me (I am from Belarus).
