In my Manhattan CAT exams I am scoring in the range of 640-660,what score can I expect in my actual GMAt xam,can I draw some conclusions?Also I am having my GMAT on 15th May,any advices seeing the score?
Our test has a standard deviation of about 50 points - so you are most likely to score within 50 points of your test scores. The official test has a standard deviation of about 30 points - same deal there (if you could take it again the next day without additional prep, you'd be most likely to score within 30 points of your prior score).
And forgot to add - good luck tomorrow! I'm guessing you probably won't see this till after you take the test but hopefully the positive vibes will help. :)
The experience is different for everyone - if nothing else, nerves affect different people differently. Plus, everybody takes a different test! So it's tough to make any sort of prediction based on someone else's performance.
