Even though DataCamp has a lot of great tutorials related to data science, the company covered up a sexual harassment scandal involving its co-founder and CEO in various wicked ways. I cannot recommend to use the resources offered by this company; I even recommend to boycott DataCamp. The web is full of tutorials for data scientists, it should not be that difficult to find a good alternative (maybe Dataquest?).
