Core, periphery, semi-periphery

I started my Intro to International Relations class this week and I already have a test on Tuesday. What am I doing to prepare? Why, I am watching Thursday's episode of C.S.I., of course. I can't believe I actually made it through all of the classes this week. It was really awkward to be the one coughing with audible phlegm in a very quiet room. Oh, and the sniffling just drew in more attention than I ever wanted. Often, my eyes would water and cross, so I couldn't even see straight when taking notes. I can't wait to feel completely normal again.
