An Unprepared Student Takes a Final Exam

There once was a student who was enrolled in a class which had a comprehensive final exam. The student, however, did not study for the exam.

Eventually, the day of the test came. The student was nervous, and when he looked at the test, he stared at it, not knowing what answers to write. After hesitating for some time, the student resolved on a plan. He got up from the desk, test in hand, and walked up to the teacher, who was sitting in front of the classroom. "Excuse me," he said, "may I have a different test?"
