Every IIM has different policy of giving weightage for the 10th and secondary PU (12th)standard marks . You need to nave a excellent CAT score to get into top IIM . If your and other applicants CAT score match then they will do the tie breaker via analysing the 10th /12th marks...

There the best opportunity to make it by having at least scoring 90 % in both 10th/12th std .Your stream does not matter here . The 90% matters.

Hope you have understood .

You can ask /comment to me whenever you wish if difficulty
