Sarmistha,
Your test scores are consistently higher than mine when I took the exam, and passed. I was really nervous as well prior to the exam, and followed what others recommended prior to the exam. I made sure that I was well rested and hydrated the day I took the exam. The day before the exam, I stopped studying around 1:00 p.m., and went to the gym for a long work out, had a nice dinner, and went to bed early. Getting plenty of rest the day before is important. On the day of the exam, I was up early went for a quick walk to clear my mind and off the to take the exam. Keep thinking positive thoughts!
Good Luck to YOU!
