Hey Aman,

The rating of college is depends on:

Placement

Education quality

Environment

Infrastructure

Fee structure

and so many things.

Since you know old is gold. We can not say about placement statistics in new IIITs. But IET-DAVV's placement is good. So many students rated very good.

IIIT Vadodara was established in 2013

IIIT Sonepat was established in 2015

IIIT Lucknow was established in 2015

IIIT Pune was established in 2016

IIIT Kalyani was established in 2014

IIIT Nagpur was established in 2016

IIIT Trichy was established in 2013

So IET-Davv will be good.

But it's not mean that in future the placement of IIITs will be not good. After all they are central government colleges. There placement in future will be also good.

Good Luck!
