"If anything can go wrong, it will"
...or something like that, that's the simplified version. There are also many versions on diff stuff u can find on the net based on that law. Found some good ones:
"When reviewing your notes before an exam, the most importamt ones will be illegible."
"Class schedules are designed so that every student will waste maximum time between classes"
"When you are occasionally able to schedule two classes in a row, they will be held in classrooms at opposite ends of the campus"
"80% of the final exam will be based on the one lecture you missed about the one book you didn't read."
and plenty more....HAHAHAHA
Finish my bio exam just now, and point 1 and point 4 above applied to me. ARGHH
