Am I good enough for Top 10 B-Schools?

I doubt it, but there is always a possibility. Your GMAT is remarkable, but you GPA is very low. I'd say you have almost no chance at Oxford or LBS, since they generally put almost zero weight on the GMAT/GRE, but far too much emphasis on GPA. If you just have a BBA and not a lot of math background, even with your great GMAT, MIT will be difficult since they are a quant heavy finance school. Princeton could be a possibility, but it will come down to professors going to bat for you and writing great letters of rec. If there is a chance of getting the GPA to over a 3.5 by the time you apply, the UK schools might still be a long shot, but the American schools will be more of a possibility. Perhaps also check some lower ranked schools, since the ones you are applying to are all very highly ranked (not saying you can't get in, but a little diversification never hurts). Good luck!
