TAKS Test Tomorrow?!?!?

Tomorrow is the TAKS test and I am nervous. For people that are already ahead of the TAKS and are in other grades above 3rd then this is for you. I am wondering what I should bring for (take a break snack) during the TAKS Test. The teacher said we have to bring a healthing snack and either a bottle of water or a bottle of water with crystal light. I was thinking of a crystal light and carrotts but I'm not sure yet but the teacher also said not a messy snack. So what do you think I should bring.
