Big difference in GPA now. However, one problem solved another one still persists. Your GMAT score is going to be the handicap right here and if you somehow find a way to rewrite your GMAT later (and get a higher score), you'll be in great shape. There are plenty of one-year programs, though most of them reside in Europe. If I were you, I'd check out Babson College in Massachusettes. Babson is a great college and offers a 1-year program. University of Florida Warrington College of Business is a pretty famous regional college as well. Other than these two, I only know of top programs that offer these, which include Emory, Cornell, and Northwestern. Northwestern is pretty much ranked number one (my own opinion) with its 1-year program and is extremely competitive. Some european b-schools include IE, Insead, Judge, Said, and ESADE. Again, your GMAT score is the limiting factor right now, which hinders your opportunity greatly at these top European and American business schools. Babson and Warrington are probably the only two that I know of that you may be competitive at.

Great BakFed ,Once again nice inputs .While 1 yr programs are priority ,i am not rigid about it .a 15-18 month program could be ok too. Also as per location i am looking at only USA. However like you suggested that GMAT is a big limitation in my case ,I might reconside taking sometime later. I am non-native speaker and need to work on my verbal bigtime .
