Personally, I very rarely, if ever, pulled all-nighters in school.  My brain skills fail me right around 9pm, usually, and anything I try to do after that involving them is pretty much pointless.  While I was a world-class procrastinator, my tests in high school usually weren’t hard enough to warrant studying all night for them (and certainly not in grade school, like Oscar’s are, apparently!), and even in college, I was a journalism major, so honestly, they really weren’t all that tough either!

Then again, based on my overall grades in college, maybe an all-nighter or two here and there wouldn’t have hurt me! 😉
