my rank is 3554 . should i opt for newer iits or older ones

Hello Harsh

According to my expertise, you should opt for old IIT colleges rather than new colleges as the old ones are the already established ones and will definitely provide you with a better placements than the new ones.

The opening and the closing ranks of the old IIT's can be accessed by clicking on the following link -

Hope that helped!
