I got a 99 on my Library of Congress Classification test (we had to assign LCC numbers to 10 different books), and my interpreters were impressed: "What a smart girl!" Which led me to thinking: graduate school, in some odd sort of way, has been easier than my undergraduate studies. I think this must be because I am in a field that interests me (and one can assume that you will understand that which interests you), so I have done well in my classes so far. It's been the same for Jon--once you can specialize in your field of interest, you start building on the base of knowledge that you established through all those years of school, instead of starting anew.
