man, i know how you feel.
my situation: this is my last semester, im graduating this december. you would think that it would be easier to motivate myself to study since these last 4 finals will be the last for a very long time(may go for an MBA or Ph.D, in the future)
it's the opposite, i have been slacking this whole semester. missing classes, sleeping in, etc....
but hey, just think, get these finals over with and you have a nice winter vacation to relax. OR, i guess if you fall, you could take the class over during winter session hmmmmmm :Q
good luck
