Wow - sorry. I would check to see if GMAC would accommodate. I doubt you can get a refund but you may be able to get a reschedule for the next few days. CALL the GMAC's hotline.
You feeling ready?
Thanks guys, I actually took the gmat exam a little over a month ago and got a 680 Q:46 V:38, but due to my low gpa (under 3.0), i was looking to retake the exam. My practice exams across gmat prep and mgmat have been in the 720-730 range, so I was hoping to hit that target.
