I am OBC candidate 10/12/grad 81/93/61 and cat 95% can I get call, if yes can I make it to final admission if done well in gd/pi

Yes, there are very good chances of getting calls from IIMs. As the number of IIMs have also increased this year, the chances are better, but you will have to make sure that you are very well prepared for the GDPI round, as IIMs require students who are all rounders and with excellent communication

You should get the call, and yes, you can convert it
