All the information available here at GMAT Club is awesome. I'm taking the test on Wednesday, and I'm starting to feel pretty good about my chances. My preparation has come down to the final steps, and I had a few questions regarding the test taking facilities. I was hoping that recent testers could answer some of these questions.
1. Is there any chance that you could run out of paper for calculations? Originally I thought it was an erasable board, but apparently people have been given wet-erase markers, and a number of pages. I've noticed that I write pretty big when I use markers for calculations, and I was concerned about the possibility of running out of space.
2. Is noise a problem at the test sites (I'll be in San Jose)? I bought some earplugs, but I don't like the way that they feel. I'm hoping that I will not have to use them.
3. Corollary to #2, do I need to be worried about bothering others? I've noticed that on certain problems I tend to mumble as I work through them (like on CR for example). If my mumbling will bother others I will need to work on that before the test.
4. Can you have drinks (non-alcoholic)

during the test, or only during breaks? I'm gonna need caffeine to get through this.
I've read the other posts about breaks and pens and stuff, so I think I'm pretty close to being ready. Thanks to any who can help with these questions.
