After each theory we are able to tackle exercises (tasks) that requires the implementation of the theory you just learned. When you complete a course a project based on real life data is waiting for you to complete. This project is set on a deadline, once submitted experienced reviewers go over your work and provide you detailed feedback outlining what great job you did along with what you should include. There is also an instructor and tutor (who is an experienced data scientist working for one of major banks) that guides you on hands on projects. The instructor answers any questions related to the course and also helps you complete each task at the end of the lessons, if you are stuck. They also have active slack community that shares tips and pointers, makes the discussion live, and asks question from which I personally learn a lot.
