How good is IIM Raipur, and what is the position amongst the six new IIMs and Shillong?

Firstly let me clarify one thing. IIM Raipur cannot be compared to IIM Shillong because the latter is out of the league and is no longer a new IIM. Its worth and placements are much better than the newer IIMs and are in the league of old IIMs. We can only compare IIM Raipur to the 6 new IIMs namely Raipur, Ranchi, Rohtak, Trichy, Udaipur, and Kashipur.

After Shillong, one new IIM that gives an edge to older IIMs is Ranchi mainly because it works under the mentorship of IIM Calcutta. The placement statistics of IIM Ranchi are a testament to the same.

After Ranchi comes to Trichy, one of the fastest-growing IIMs. It has a decent placement scenario and a better professional approach.

Raipur and Udaipur are almost similar and are better than Kashipur and Rohtak. Raipur especially enjoys location advantage being situated in the capital of Chattisgarh. The faculty base is also quite learned and the institute has proper connectivity.

Kashipur has many connectivity issues but is famous for its guest lectures and interaction with industry experts. 

IIM Rohtak is the last in line mainly because of its pathetic placement scenario which overshadows its vicinity to Delhi.

So the final order is

Shillong>Ranchi>Trichy>Raipur=Udaipur>Kashipur>Rohtak
