Materials (video and written) only partially prepare the student for the quizzes and course projects.

Not as clear and straightforward as R Programming. But definitely a worthwhile course to look at.

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

It would be better if for each function there were more examples.
