Dear Vincent, There are 20 IIMs and the conventional ones are IIM A,B and C. Did you know that IIM C has had 100% summer placement this year? IIM A has been one of the oldest IIMs in Indian Management history. It is starting its Summer Placements from November 1st and we should see how it might turn out. Now IIM A plans on starting PGP in Advanced Business Analytics. IIM A has evolved itself and kept itself abreast among all the IIMs with its innovative courses and feeling the pulse of the Management world. So, if I have to pick one among the 20 IIMs, it will be IIM Ahmedabad.
