Hey.
Considering your rank in entrance exam is 2313 and you  don't seem to have much chances for admission in UILS, Chandigarh. 50% weightage is given to 12th boards marks and 50% to entrance marks. Even if your marks in boards are really good, your chances are less.
There are 120 seats each for BALLB and BCOM LLB in the Chandigarh campus, 60 each in regional centres. So for the Chandigarh campus if your rank in the BA LLB merit list after combination of both scores is uner 150-180 you'll have a fair chance in the first counselling itself.
And with your rank and marks in boards your chances seem less. Wait for the final ranks to be out for a better estimate.
Best of luck
