who will grade the graders?

Have you ever wanted to crack open a litigious skull and see what goes on in the mind of a law professor?

This is an off-the-charts A+ answer. First, the student directly and accurately identified the precise legal question and exactly what makes it hard. Second, the student explained exactly why the two cases point in different directions without resolving the question. The student clearly gets it: she seems to know the relevant law perfectly and has mastered applying that law to the facts. The answer is so good it's like the student read your mind — this is exactly what you were thinking when you wrote the question. And the student did it all in the context of a high-pressure 3-hour in-class examination. Wow, that's incredible. As they would say on eBay, A++++++++.

No? Well, you still can.
