You know your doing something wrong when your overjoyed to get a 74/100. I was sitting in my desk, dejected look on my face, because I knew that I had failed. And then it turned out I hadn't. :D
That's an awesome feeling xD In tech class I once thought I had failed a test, so being a jokester I asked my teacher "How bad did I fail?" while picking up my test and he looked at my like I was crazy and said "You fail my class?"
