Seema,
everyone is nervous. But being overly nervous is not a good thing. A little anxiety is good for you since the sympathetic nervous system stimulates the adrenal glands, specifically the adrenal medulla, to release epineprine and norepineprine which start up the "fight or flight" response. This increases your heart beat, pushes blood away from the GI tract and takes it straight to the skeletal muscles. Skeletal muscles are multinucleated, striated, and are under voluntary control. Meaning that by using the skeletal muscle you will be choosing either A, B, C, D, or E for the answer choices on August 27. After August 27 the parasympathetic nervous system will kick in and remove blood from the skeletal muscle and take it straight to the GI tract to "rest and digest." Just think about after you are done. Think positive. Just think, in this response you just learned several more concepts and you are even more prepared for the DAT. Don't worry you will do fine. Worrying does not achieve anything.
