Hello,

IIIT Hyderabad is one of the finest institutions in India providing undergraduate and postgraduate courses in CSE, ECE and other related disciplines. Every year students are attracted towards the high package offered by the college and thus the competition of UG courses in very tight. The closing ranks is below 100 for all the courses and thus I would suggest you score above 99.5 percentile in the JEE Mains to even hold a chance for Btech from IIIT-H. 

Hope it helps
