Hii my jee main rank is 66467 general and 18564 obc can i get admission in nits or iiit

Hello,
On the basis of your rank in jee mains 2018,Chances are quite low.But you can still try to take part in josaa counselling and try till last round because it may happen that seat remains vaccant for admission in NITs or IIITs.
Apart from this,you have high chances if getting top private colleges through state counselling.
Good luck.
