What percentage is needed in class 12th for MBA from IIMs?

I think to join IIMs u need to score good percentage in CAT exams(above 90 percent) and do well in GD & PI. if u can do well in these 3, I think you will be able to join any good colleges and the graduation marks won't matter tht much

Your Graduation percentage matters the most.

They say 70% is required in 10th and 12th. But I don't know the exact thing. I think CAT/GMAT scores matters. And 10-12th around 60% will do.
