Hm.... Your score seems to be in line with Kelley but UNC average is 700 and that may warrant a retake (though your stats are pretty impressive and you may be OK).
Look here for averages:
The usual question about retakes is - do you have the time for it?
If you do, then it may be worthwhile to try for UNC and for a higher score, so it is out of the question but if your time is scarce and you need time to finish essays, then I would focus 100% of your time there.
Thank you very much for you reply BB.
Can you please let me know the chances for Carlson, Minnesota?
I do not have time for a retake as I will be busy with tight work schedule in the next couple of months. Also, I do not want to retake for 20-30 points.
I was told that I can look at the 80% score range if the profile is good. For my profile, can you let me know the top schools where I have good chances?
