Testing

So I've got this test coming up called the Qualifying Exam. Basically, it's where they test my ability to withstand grad school/doctoral pressures by quizzing my critical analysis on six books from various times and places of Hispanic literature. Is it okay that there is some minor indignation that I have to take this? Aren't I smart enough that you can see I'll be fine? My older, wiser friends who have passed through this exam say it'll be a breeze for me, and I've believed them up until this point, some two weeks before the exam. What if it's not a breeze for me? What if I lock up and am suddenly inable to communicate thoughts in Spanish, or worse, have no thoughts and opinions on whatever I'm being asked about? Other times I shrug off the responsibility of studying and play Final Fantasy until I have a motion-sickness headache. 'Cause that's a little more rewarding.
