My teacher is going to give my cl a test with no question?

I've heard rumors that my english teacher is going to give my cl a test with no question. He is apparently going to hand us a blank piece of paper and tell us to "Wing it." Luckily I have a friend who was in his cl last year, and he says we are supposed to write an essay answering a question of our choice in the essay. ie: who watches the watchmen, or something along those lines. My teacher is always saying things like, "With absolute freedom, many would freeze up and fail." Or something like that, so I deff. believe he will give us this test. :\ I've never had a teacher like this before, he is all about having us thinking outside of the box, and not feeding us info. which we spit back out on tests. Soo, I'm totally stuck. What should my quesion be and how should I go about writting an essay that answers that question, without coming right out and literally writting my question down? Thanks. [One question I was considering was: How do you fail a test with no question? But that would be even more complicated and I'm not sure how I would go about making an essay out of it, but it would be funny if he got the meaning of it(;]
