Hello Kokila, 

             National Test Authority (NTA) conducts jee main paper 2 for admissions of students to NITs spread across the country 

             But this doesn't mean you l get only NIT through this. 

         There are many colleges under state Universities that accept applications for b. arch through jee main score thus enabling you to fill up application form of government colleges witj b arch course through jee main paper 2 scorecard 

          Also with this rank and category you have chamces of getting NIT too.  Now predicting the particular NIT would seem difficult and meaningless as almost every year the trend changes. 

       Register for counselling whenever the portal opens and see what best happens.

GOOD LUCK
