Given the question, I will give the student full credit for being creative :). It would be different if the question is "Find the value of x".

It reminds me of an exam that my friend had (at Berkeley if that makes any difference). The question was "Explain what bravery is". The rest of the class wrote 1-3 pages of explanation. My friend only wrote "This is bravery". She received almost a full mark, everyone else had much worse score. The lecturer told her that it was the best answer ever given by a student, but there's no way he would give a full mark on a one sentence explanation.

The urban legend I heard was that it was Berkeley and it was a philosophy final. The professor put a chair on her desk and told the students to write about "the chair that wasn't there".

It wasn't Harvard, was it? I thought it was Stanford, and the student answered none of the other questions...

One I heard at Berkeley involved one of those very large 300 student classes. There was a strictly timed exam and one student went late. When he went to the professor to try and get him to accept his exam, the professor was standing there holding all the exams and said "I'm sorry you're late, I can't accept your test". The student said "Do you know who I am?", the professor replied "No" so the student said "good" and stuck his exam in the middle of the pile and ran out.

Yes it was :) And one can easily get expelled from a B school for incorrect citing ;)

i would give him full credit just for making me laugh so hard. this made my day !!!
