Hello!

For getting any of these NITs or IIIT Hyderabad,  you need to get the required percentile or rank in the JEE mains examination since all these colleges have that as one of its eligibility criteria.

Apart from that the boards cutoff marks and the JEE mains cutoff should be satisfied to het an entry in these.  For that , a special counselling called JOSAA counselling is done.

If you qualify through all these, you can get admission in them from whichever category you may belong.

Hope this helps and Good luck!
