Dear Friends,
I gave my gmat yesterday and got a horrible score of 510. I was thinking of applying to US 2nd tier colleges for fall 2010 . But with such a low score I doubt if i would even get a interview call. About my profile , I have 5+ years of IT experience including 2 years of Onsite experience .
Can anybody suggest me some colleges in US and Canda taking this score? improving from 510 to 650 is a long way for me and I want to apply for MBA this year...
Any suggestions would be appreciated..

Regards,
Rohit
