I would urge you to retake the GMAT. Think about it, what do you have to lose? 250 bucks?
Take a course with a score improvement guarantee and then retake the test and you will either improve or get your money back.
Don't forget that the GMAT is a leading factor for your entire future...
OptimusPrep, thank you for adding to the discussion, but I think your whitewashing the issue a little bit.
It's a bit extreme to say that the "GMAT is a leading factor for your entire future." There are plenty of things that are way more important, such as family, friends, play, happiness, smiling, adventure, and eating well. The GMAT is merely a stepping stone in ones career, and one that most likely will not matter once a person is admitted to an MBA program. It is a means to an end—not an end in and of itself.
Ultimately, Amy needs to carefully evaluate what programs she wants to attend, the average GMAT score at those programs, and the strength of the rest of her application. Also, $250 is not a small sum of money, and you don't get that money back when you take the test and get the score that you are hoping for.
The decision to retake the GMAT is no small thing and should not be minimized or glossed over.

Again, thank you for entering the conversation and providing your ideas.
