Gmat 600
Work Experience More than 2 years.
Bachelors 3 yeras and Disgustingly Low GPA..

Applying For some of the colleges like Florida International and naveen jindal, and also stanford which I dnt have much expectation now as im GMAT didnt get pass 600.

Which kind of universities should I apply in?? Can we find spring session colleges also for MBA? Im pretty sure any university would make me take a PG or 1 year diploma course, so can i get in those courses in January?

Can you retake the GMAT? If you have a low GPA, adcoms will want to see some kind of other evidence that you'll excel in an MBA program. A stronger GMAT can help ease their worries. Yes, a diploma program or something along these lines, if you do well in it, could help in this area as well.

In general, only a few US MBA programs offer spring intakes. The closest I could find to a list was this:

Looks like Columbia (the J-term option), Fordham, and St. John's all have full-time MBAs with spring intakes.
