I scored 93 percent in 10, but only 74 percent in 12th. If I graduate with more than 80%, and perform well in CAT, do I have chance to get shortlisted for top 3 IIMs, i.e., IIM-ABC?

I am afraid if low score in class 12 can hamper my chances for top 3 IIMs. Also, please let me know what percentile in CAT will be needed by me.

PS- I am a general, male, having no work-ex.

Thanks!
