The Bihar Public Service Commission has released the final answer keys for the Prosecution Officer (Preliminary) Competitive Examination under Advertisement Number 13/2026. Candidates who appeared in the preliminary examination held on 15 July 2026 can now match their responses against the final keys. The keys have been released for both papers of the preliminary examination — General Studies and Law — and are displayed on the official BPSC website. Because these are the final keys, they follow the review of objections raised against the provisional key, and they are the version candidates should use to estimate their scores ahead of the result. To check, open the official notice for Advertisement Number 13/2026 on bpsc.bihar.gov.in, select the paper attempted, and compare answers question by question. Keep a copy of the key for reference, since the result stage will follow this step. Candidates should not trust keys shared on unofficial channels — only the keys on the Commission’s own website are official.
