Some test centers provide coffee, sodas, pastries, and light snacks . . . but don’t count on it. Bring a small bag with enough to get you through the entire exam. A big bottle of water is essential. Also, consider bringing a soda and some snacks, a sandwich, energy bars - whatever you like to snack on that replenishes and renews you without making you too thirsty. At most test centers, you’re allowed to eat at the back of the room. Avoid crunchy or noisy foods that could disturb others in the exam room.
