For a UR candidate it is generally advised to cross 160 and for the OBC 153 ,SC 143 ,ST 123 , NRI/OCI 144 .

As there are only 200 seats available and the cut off depends upon the number of students appearing and the toughness of the paper . 

I would advise you to score as much as you can as there is no surity the cut off will fall .

Hope this helps.
