Thanks for the reply...I agree with you obviously if someone were to be taking the test for you. I just think its crazy that the GMAT can decide your score is "too high" based on a previous test and just cancel it without any evidence of cheating. That would seem like perhaps the most frustrating experience for somebody who made a high jump. Even on this board I've heard of people going from the 400's to 700's so while it is not common, I would say it does happen without cheating!
Let's say somebody took the test without studying and then took it after studying again.....Seems logical they could increase very very high amounts.
Just overall shocked that the GMAT would put a policy like this in place..it almost discourages hard work if enforced!
It is very hard to increase by more than 200 points.
Over the years, GMAC has compiled statistical tables that say only XXX people increased by X points and so on.
For example if you take the test on Sept 18 and get 450 an then on Oct 19 and get 760 - that's very suspicious as I can't imagine anyone be able to improve so much in such a period of time. However, if you took it 3 months later and you have 200 or so points, then it is probably acceptable.
They may still flag your result and review the exam conditions (footage from the cameras, etc) to make sure you were not "helped" but I don't think anyone legitimate has any reason to be concerned. GMAC has been very helpful and cooperative with students lately. It has been very pleasant to work with.
of course if I have a score of 300 (for istance) last year and this year 720 why i can't improve ?? should be not reasonable by GMAC cancels your score. There are CCTV cameras, your digitally firm and a lot of time to improve in between.
