It's a survey class, you'll learn the foundation of communication studies from the definition of communication up to it's effect in politics, culture, and society. It's not an 'easy' class, per se. You have to read a lot of readings, but it's pretty interesting.
I didn't have that prof, but for my midterm it was two essay questions, and the final was two or three essay questions. If it's communications, it will most likely be essay format.
