Hello Arjun,

In the second counselling, if there are not a lot of vacant seats, then the cutoff dipping to 498 has very slim chances. In PU BA LLB, both your merit in the 10+2 qualifying examination and your performance in the entrance test matters equally by 50-50% weightage. So, as of now, it seems that you have fewer chances of getting admission in the second round. However, don't lose hope and keep looking for other options while waiting for the cutoffs. 

All the Best!
