Essay

For a short mid-term survey of his students, a Graduate Student Instructor has put four questions on a piece of paper. He is planning to hand these out this afternoon. The last two questions are: (1) "What grade do you think you are getting in the course?" and (2) "What grade would you give the instructor so far?" Both questions can be answered with A, B, C, D, or F. What is a potential problem with these questions?
