Hello,

The JEE score can be used to take admission to IITs, NITs, IIITs and GFTIs. Here it is only the IITs that consider for JEE Advanced. For all others JEE Mains score will work. For admission to all the afore mentioned institutes you should register for the JoSAA counselling which starts by second week of June 2019. Every institute will have specific opening and closing ranks for each course across several rounds. For JEE Advanced 30% marks altogether and 10% marks separately in three of the sections is considered as eligibility.
