Hi Tejaswi, 

                 See it's not always that if topper has more marks so u l not get a seat in college. During counselling there are many students who back out  or fill different choices. 

 Thus you must always attend the counselling and hope for the best.

                  Your score is not that bad that u will not get amy NLU, of course u may get NLU.

             And for your idea about dropping see you must always attend counselling and then take further decisions.  If you really want to go for NLU and somehow do not get seat then u may drop and go for it next year. 

GOOD LUCK
