The two local centers I've used in Denver give me 2-3 sheets of blank paper and a pencil. After the exam I have to turn the paper and pencil back in. Well, not necessarily the pencil. I think I walked out with one.

You have no access to BOL, the Internet, and I have had to leave my cell phone with the proctor. You are typically under camera view the whole time.

As Jack mentioned, don't worry about the score, the questions, the passing. Study and practice. You need to take the whole test, so all you can do is do your best.
