I've never posted here before but I read a lot of posts here when thinking of retaking the GMAT so I figured I would post my story and see if it helped anyone.
I orginally took the test in mid-March and got a 710 (Q:76%, V:95%). I had studied for about two months about 5 or 6 hours a week largely using Manhattan GMAT
. I wasn't unhappy with the score perse but I had done better on practice tests and since I have a lower GPA (3.1 but from an Ivy) I thought a higher score could help. A lot of my friends said not to retake it but I just couldn't get the feeling out of my head that I could do better. I decided to just relax for a few weeks, then pickup the same schedule and take the test in mid-april and focus on the Quant material.
I took the GMAT again a few days ago a got a 740 (Q:67%, V:99%) which I thought was weird because I didn't study for Verbal at all. While I'm pumped to get the higher combined score, I think the disparity in the Quant and Verbal scores probably means it really didn't improve my profile much. But I am very happy I retook it because it would have always been in the back of my mind if I hadn't.
I know there are a lot of people struggling with weather or not to retake it after a low 700s/high 600s score. My opinion is that if it is bothering you, go for it. At least you'll know instead of thinking that you wished you had retaken it if you don't get into the school's of your choice. Just my opinion and hope it is helpful to some people.
