Dear aspirant,

IIT Hyderabad or any other IITs, they only consider JEE advance rank for admission procedure. But to give JEE advance you need to clear JEE mains. After clearing JEE mains only, you can give the advance exam.

Your JEE advance rank is the only criteria through which you will get an admission in IIT Hyderabad.

But, there's another institution called IIIT Hyderabad, it only considers JEE mains rank. This institute is as good as any other IITs.

Hope this helps!
