From Rate Your Students, via Ernie's 3D Pancakes:

My classes are large, so I mostly use multiple-choice tests. One day, being one question short of a nice round number, I used this question: "The answer to this question is D. Be sure to mark D on your answer sheet." The offered choices were: (A) This is the wrong answer. (B) This is the wrong answer. (C) This is the wrong answer. (D) This is the correct answer. Be sure to mark it on your answer sheet. (E) This is the wrong answer. About 20% of the students got it wrong. One possibility is that they couldn't read any English. Another is that they didn't care. But one student had the courage to admit that he always marked B for every answer (true, that's what he did) in hopes that all the answers were B.

One wonders how these students would have performed on Jim Harrick Jr.'s basketball exam?
