hello greetings

At just 46 marks you cannot expect a NIT college as the competition is very stiff and lakhs of students are interested in taking admission in NIT therefore with just 46 marks it is impossible to get admission in to NIT, some better you try for next attempt of JEE main you an appear  for other entrance exam and take admission in to other institutes.

Hope this helps all the best
