Not too easy. Not too difficult.
I recommend reading the mandatory texts offered on the course website, going to discussion sessions to shape your understanding and never stop thinking about the issues covered in class. And never skip a class.
I learned about different theories on the causes of war, and different peace proposals offered by the past and present great philosophers. I also learned how to read a statistical table, and what it means for a relationship to be statistically significant.

Advice for students:
Always go to lecture, and write down most of the information the professor is telling. Read ahead, never postpone the readings. Every time you come back from class, read again your notes and try to memorize the information so that you don't have to study so many new information right before the exam starts. Go to class discussions and try to be an active participant. Try to voice what are your opinions regarding the issue and hear what other students are also getting from the class. Also, visit office hours just to chat with the professor your ideas and whether your understandings are correct or not. Finally, never give up.
