I was appeared for GMAT exam few days ago. It was one of my worst experience of examination in my life. My exam centre was Ahmedabad, India. (Code 8092)) as Mumbai, India is 500 KMS from my city BARODA, INDIA. I was surprise after see exam center. It was in the college. The administer who conduction exam was young college student (may study in same college). I found she was taking so much as her many friends come to meet her. I instruct her many times but no effect. One more bad luck with me, while I was doing RC section in verbal part power suddenly off!!!. I read it took 25 minutes to start it again because of UPS failure. I was afraid that my exam would save or not? In that tension I frusted more and it directly effect my remaining exam performance negatively. Finally my score was 370!!!!!. I was hard working from last 7 month for GMAT. I got in Powerprap 2006 in range of 600-650, Kaplan 550 -650. But in real exam in 370. I never got this score in my any practice. During real exam so much disturbance from outside as college and also from administrator. Also I found during exam she was doing chatting with her friends from PC where she has to look student by web cam. I am so much upset. Please help me. My 6-7 friends who gave exam near to my exam date they have same experience. Culture festival was just front of examination centre and one of my friends exam was going on same time. He got so much upset while exam and he scored just 420 (second time same centre) my other friends got 460, 380 like these in exam. We all hard work toghter from 6-7 months and we never got less then 600 in practice exam. Please help me. I want to apply for Fall 2006 and dead lines are near.
