Hello Manas, 

137 is a pretty good score and the Rank Predictor tool mentions that your rank might be somewhere around 1-202 considering you are from the Unreserved category. 

With this kind of rank, you have a fairly good chance of getting into some top NLUs according to the previous year cutoff trends.

Here are some which you can consider - 

• NLSIU Bangalore - Opening and Closing score of 135.5 and ranks from 58 to 60 respectively.
  
• NALSAR Hyderabad - Opening and Closing score of 128.25 and 128 with ranks ranging from 130 to 135.
  
• NLIU Bhopal - Opening and Closing score of 120 and 118.75 and ranks from 355 to 395.
  
• NUJS Kolkata - opening and closing scores of 122.5 and 122 and ranks from 215 to 240.
• NLU Jodhpur -  scores 120 to 118.75 and ranks from 350 to 400.
  

These are some options which you can refer because a lot of government and private organisations accept admission on the basis of CLAT score. These NLUs are the topmost in the list and hopefully, you can grab a seat in one of them. 

All the Best!
