Stress cаn effect yоur perfоrmаnce оn exаm; it is called test anxiety. The cortisol levels in your blood go up when you're stressed, sending you into a fight or flight response. This diverts oxygen from your brain (where you need it to think) to your limbs (where you need it to run or fight). To decrease your stress levels so you can think more clearly for this exam...all you have to do is take five deep breaths. Inhale for a count of two, exhale for a count of five. Do this: Inhale (counting to two). Exhale (counting to five). Inhale (counting to two). Exhale (counting to five). Inhale (counting to two). Exhale (counting to five). Inhale (counting to two). Exhale (counting to five). Inhale (counting to two). Exhale (counting to five). Now you are calm and your mind is more ready for this exam. You can DO it! I am rooting for you! The answer to this question is true.
