hello,

Cutoff is not mentioned. The merit list have names of the students  who have been shortlisted for the coming rounds.

You can check the list from the official webpage of bihar public service commission.

Here is the link:- http://www.bpsc.bih.nic.in/

You will get all the details and notice for every exam from there. You can check it from there.

For interview there is nothing like cutoff. It is performance based and totally depends how you answer the questions and how the evaluators will evaluate you.

Hope it helps!
