Dear student!

According to your rank , you will br able yo get all IIIT and also your home state NIT'S . 

In case of placement perspective, you should take/consider

IIIT Trichy  -- why?

Iit trichy is located in campus of India' best Nit ,

Namely NIT TRICHY. And both College placement are done together.hence you will get a very largepool of companies to choose from.

IIIT dm Kanchipuram-- It is mentored by Iit Madras, 

Which is ine of the most prestigious college of india

Also they have a collaboration, in which few toppers in each field( cs, ece) will be taken to Iit madras for 3 semesters. ( 6,7,8 semesters). Also you will be placed from Iit madras only if you get selected in that 3semester program .
