Hello,

Sorry but you won't get an admission as you have to get 70-80% in your 10th and 12th  to get an admission at any IIM campus.  You can try for other private institutes or government colleges which offer MBA degree. They can consider it. But there will be a screening test for it else you have to appear exam like CAT,XAT,MAT, or universities have their own exam to intake students also.

No need to be feel  bad for it. You  can do best in future for sure. Keep on trying. We can't change rules but have to follow them but we can change our performance with our hardwork.

Hope it helps!
