Hi takeone,
I got a rejection letter from Haas with a 610 GMAT score. Hovewer, my admission consultant told me that my GMAT score was not the only factor. He said also, that my GMAT score is compared with all the international applicants... Since you are from India, and I think there are better scores among the indian applicants to Haas than yours. I suggest you retake only if Haas is your first choice and you really want to enroll to that school. I will go to U. of Southern California. I am a canadian citizen and I know about other canadian friend who got accepted into Haas with a 670 score. Hope this helps.
regards, roger.
