Happened last weekend with my Art History class in college.  I studied all weekend and knew there was just too much to remember.  I studied anyway and on Monday I took the exam.  I left feeling like I had guessed on a lot of answers.  On wednesday we got the results back...surprise-surprise...57%   
I'm so glad I wasted all last weekend inside studying for a fucking 57%...makes me want to study more for the next exam!
