There was a student who was talking to her head of department outside the library one day and the Head asked her how his Economics course was going. The student replied that it was no problem and that she was sure she would do really well in the test because she knew all the questions.
The Head was very surprised and asked what the questions would be, and the student listed 10 questions that she said the teacher would ask in the test. The Head went straightaway to the teacher and started to berate the teacher for giving out the questions before the exam. The teacher protested, saying that he had not given out any questions, but when the Head listed the questions that the student had said, they were exactly what the teacher had written down for the test on the paper that was in his office.
The Head and the teacher decided that the student must have slipped into the office and copied the paper, so they called the student up in front of a committee on charges of cheating.
The student protested her interest and said that the teacher had said there would be ten questions on the test and had made clear what questions they would be. The teacher protested loudly, „I never said what questions would appear on the test.“ The student replied, „Oh yes, you never said it, but you showed it clearly. When you were talking about a topic that would appear as a question, your voice changed and you moved to a different part of the room.“ So I simply put a star next to those topics, and that’s how I knew they would appear on the test.
The whole committee agreed that the student had done nothing wrong, and was in fact to be congratulated on her careful attention to detail, so she was told that she didn’t need to sit the test at all and would receive full marks because she had already shown how well she knew the material.
