My feeling is that if you have been out of college
for a while, and you are not going into something really academic (history, as
opposed to museum studies, for example) then you don't need to worry too much
about GREs.
You have to take them to get in, of course, but
your program is going to be looking at you, your accomplishments, and your
interests a whole lot more than your performance on a high-stakes 3 hour
test.
I took mine whilst still half asleep, without
benefit of food or coffee, and totally stressed out after having overslept and
almost missed my bus to the testing site. Did as well on them as I did on
my SATs, for which I was a whole lot more prepared.
Got into graduate school.
Good luck!
