Hey greenie. Decent score but the really low %ile in DI would have affected your chances in all IIMs.
Though I've been out of touch with the MBA scene for a while now, just check if MICA, TAPMI et al have wrapped up applications.
At the same time, my advice would be for you to hang in there for another year. Seriously. Take the CAT again properly next year and put fight to get it right at all three. A quality MBA with another year of work-ex is leagues ahead of an MBA you settled for with your current score. PM me if you want any specific help.
All the best!
