Hey.
Considering your score in entrance exam is 55.75 and that your Graduation score is 51% you seem to have a less chances for admission in PU.
Your combined score will be around 52.5 without any weightage if any.
There are 300 seats each for LLB in the Chandigarh campus, 60 each in regional centres.
So considering the fact that your entrance score is good but your graduation marks are quite low so your chances seem a little less. There are not much chances for Chandigarh campus but you might have few chances for regional centres in the subsequent counselling. Sowait for the final ranks to be out for a better estimate.
Best of luck
