Hello Saumya,

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.

The cut-off for the year 2018 can be checked through the given below link.

Note : The total marks for Panjab University BA LLB 2015 is 100, where every correct answer will be awarded 1 mark and for every incorrect response 1/4 th marks will be deducted from the total scored marks.

The cutoff of PU BA LLB is the minimum marks required by the candidates for seeking admissions in five-year integrated law programmes offered by the university. PU BA LLB Cutoff 2019b will be calculated by the university by keeping certain factors in mind like the total number of test takers and the maximum vs minimum mark scored by test takers of the PU BA LLB Entrance Test , besides a total number of offered seats in the university.

Hope this helps!!

Good Luck :)
