Although IIIT HYD IS ONE OF THE BEST COLLEGE OF INDIA FOR CSE BUT I WILL SUGGEST TO GO WITH IIT GANDHINAGAR AS IIT TAG AND ALSO VERY MUCH EXPOSURE BUT YOU CAN ALSO LOOK AT THE PLACE, FOOD WHERE YOU ARE GOOD TO GO.. IT WAS JUST MY OPINION LET YOU AND YOUR SON TAKE YOUR TIME.I WILL JUST ADD ONE MORE POINT THAT DON'T BE TENSED MUCH AS BOTH THE OPTIONS ARE ONE OF THE FINEST COLLEGE..
