IIM

Dear Akash,
See if you managed to score anything above 95% then also you need to have some social activities experience as well because apart from academics they gives weightage to extra curricular activities as well.
All the very best.

IIM Bangalore will conduct CAT 2016. The official notification will be out in the month of July.

Yes there are scholarships both at central and state levels.Moreover there are financial institutions to offer study loans .What one requires is hard work and get good job soon after degree and IIMs have the repo for the same.The loan can be easily paid back.

Hi, You have to appear for CAT

According to placement and other facilities iim is better but where do you want to go its your's choice.

You seem to be on the average side for an ST candidate. Given your performance, I would guess the range to be between 90 percentile to 97 percentile. To be on the safer side, you should aim for higher percentile 99.99. Please note that the cutoffs change every year and it is impossible to guess the cutoff. Hence put in your best foot forward.
