Help for Final with "The Pit and the Pendulum" by Edgar Allen Poe?

I have a huge final on the horror story "The Pit and the Pendulum" by Edgar Allen Poe. I've read the story, but I cant imagine any questions that will be on the test. Our teacher did hint that we should understand the "deeper meaning" in the context of the story. Has anyone took a test on this before? What were some of the questions? THANKS.
