what are the difference between IIM and Other B-School???
i think there are no difference because all the B-School are same. only difference is that IIM wants only intelligent people. if IIm guts to take average student, give the knowledge. u think that why IIM take cream student. frndz college kuch nhi krati jo krna hai khud ko hi krna hai.
