hello bisman.

There basic criteria of calculating the marks for making the merit list is-
 ● 50% of the marks scored in 12th
 ● 50% of the marks scored in the entrance exam.
So, even if your expected percentage in 12th is 75%, your chances might get increased if you work hard for the entrance. And for scoring good marks in the entrance you just need to have basic knowledge of law and current affairs.

And in case you are not able to get admission in UILS, Chandigarh, you might get admission in UILS, Ludhiana or Hoshiarpur.

thank you.
