you probably would have failed anyway

why?? and sucks OP, but you definetely deserved that. if you were busy with 13 hours of reading the wrong book, it was most likely first time you've ever studied. first thing you do is find the right book - and you don't just read it, you take good notes along the way to go over. also, if you didn't know two different books (with complete different stories in history) you obviously weren't paying attention in class to see what you were learning about. next time, just pay attention >.<

i don't understand how people do that :(

That's why you never study for a test 13 hours straight. If you don't understand it in a hour, you never gonna understand it in 13.

i feel your pain i did the same thing and then proceeded to write a 7 page paper on it too. epic fail.

I second comment #3... =S

gosh, it must SUCK to be you

lols

had the same problem with the spark notes for "The Invisible Man" and "Invisible Man"

maybe pay attention in class next time haha how do you mix up history books. also shoulda talked to friends about it

Drop out.
