Hello There ,

You can go for josaa counselling , you might get some new iit in the later round in some low branches although there are less chances for that.

JEE Advanced score can be used to take admission to many colleges other than IIT which are these -

1)IISC Bangalore

2)IISER

3)IIST Thiruvananthapuram

4)RGIPT

5)IIPE

From these , you have chances to get iist , iiser , rgipt and iipe , so you can try for them .

Apart from that you also have your jee mains score , try if you can get Nit or IIIT  or GFTI according to your mains rank  .
