Hey.

As per the last year trends for admission in Delhi University for 3 year Law the cut off for admission for the OBC category was a rank of 141 in the year 2018. And in the year 2017 the cut off rank was around 210 for OBC. So the cut off changes each year due to similar factors and you can expect a similar range this year too. Considering your score chances seem less but you can still try in the subsequent counsellings as this year it might be different.

Best of luck
