i have scored 86 percent in boards.and expecting to get 20 in ba llb exam? do i have chance to get admission in regional centers

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.
Though the cut off chances each year according to the difficulty level of the paper and the level of Competition, only a fair estimate can be made regarding the marks.
So if your boards score is 86% and score in entrance 20 your combined score will be around 53 Considering which you don't have any chances for UILS Chandigarh. Chances in any regional centres is also not much.
Best of luck.
