Pretty easy, overall.
Every student, irrespective of majors, should have a basic grounding in Earth sciences. Planet Earth offers a good and broad overview of earth and environmental sciences to non-science majors.
The course is a good mix of theory and laboratory work. Teaching styles and content will vary depending on the instructor picked to teach that course each semester, but all in all, students can expect to come out of the class knowing how to read a map, knowing and understanding what climate change is and means, knowing basic geology and knowing enough about hurricanes/floods/volcanoes and other natural calamities that they may someday be faced with.

Advice for students:
Read chapters of the book before going to class. Learning should not be for the sake of grades only; so pay attention. Do the labs as these carry a good chunk of points and do not miss assignments.
