Dear sumit,

Though you have failed in 1 or 2 subjects in your board you can write your Jee and if you have done a great job in jee..

You can get a seat in any IIT r NIT....

But before taking admission in NIT IIT...you need to pass your board subjects....If not your hardwork fails...

So...please work for JEE now...then clear your board...

And the main thing is you need minimum 75% of your board marks...

-All the best!!
