I appplied through the Consortium to Stern, Tepper, and Tuck...with a dismal GMAT score of 510! I know I can get AT LEAST 680 if I take it again in Feb. GPA 3.2 zero work experience. "Studied" for the GMAT in 2 weeks. Should I tell admissions tto wait on me better score?? 
Also check if work experience is required or not for each university you applied at. Since you have no work experience and you believe you can score much higher on the GMAT, I'd most likely consider taking the GMAT exam again so that you score higher and have a greater chance at getting accepted!
Good luck
