Last semester a student took macroeconomics and didn’t have a clue what he was doing (as cited on the final exam). There were 80 multiple choice questions. For some reasons he decided to play the game of probability and choose the letter “A” for everything. In that game, the only thing probable was that he failed.
The following day, the professor asked to see him after class. “Is everything okay?” “Sure,” he said, “why? “Well, here’s your test,” he said and handed him a piece of paper that was covered with red ink. “Can you explain why you chose an ‘A’ for everything?”
Knowing that there was nothing he could do at this point, he said, “Well, I’ve always wanted to be an ‘A’ student.”
