• Answer:

  relax.. nothing is wrong with you. before the exam starts, breathe deeply and calmly summarize everything you have studied. you must keep yourself calm and cool. Try deep breathing, remember to exhale, and imagine parts of your body relaxing one by one, start at your feet and work your way up. Breathe and exhale slowly to a count of eight for each.you'll calm down once you're positive you know exactly what you're doing.
