Hey.
Admission in Panjab University, Chandigarh for tge course of BA/BCOM LLB is done on the basis of both your result in 12th boards and entrance exam. 50% weightage is given to both the scores.
So as your boards percentage as well as your entrance exam's score both matter equally. As most of you have already got your both results a good score in it will put you at a great advantage.
There are 120 seats (both BA and BCOM) 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.
Your combined score will be around 65.35. This year the cut off might be lower as the entrance scores have been low too hence you might have a fair chance for UILS.
Wait for  the  final ranks after the combined scores for a better estimate.
Best of luck
