Looking broadly, there are five major parameters that distinguish IIM A as the best.
Quality of Intake: As the most sought-after B School, it attracts the most talented and passionate students. Good input results in good output. Peer learning is also more effective.
Incredible Faculty Members: It has had the best set of on-campus and visiting professors. Even guest speakers are the best in the business.
Infrastructure and Facilities: Because it has always been at the top, it has always had funds to invest in the best infrastructure. The fees are high, but there are government grants available.
Alumni Network: The best jobs are given to students. They will now want to return to their campus and recruit students. This aids in placements. Furthermore, these individuals guide junior batches, which means you are being guided by the best.
Finally, IIM A is a brand that has proven its worth. People are aware of it. These perceptions are difficult to overcome, so only a small number of people prefer Bangalore or Calcutta over Ahmedabad. A has an unrivaled sense of pride.
Among the other IIMs in India, IIM Ahmedabad created a reputation as the best marketing school by providing good academics.
One of the professors from this institute is a co-author of a Marketing Textbook used in top B-Schools, i.e. Marketing Management: Philip Kotler, Abraham Koshy.
Over the past decade, the media has taken a fancy toward IIM Ahmedabad. And the institute has lived up to its reputation.
IIMA is the toughest B-school, and around 0.2 % of applications get selected here. If we compare the CAT percentile scores of other top IIMs, then it can be seen that the cutoff is similar.
