OPSC OCS Mains Exam 2026: Schedule Out, Exam from 29 October

The Odisha Public Service Commission (OPSC) has issued the Main (Written) Examination programme notice for Odisha Civil Services-2025 (Advt. No. 05 of 2025-26), announced on 29 August 2026. As per the schedule, the OCS Mains exam will be conducted from 29 October to 7 November 2026, across multiple days covering compulsory language papers, General Studies papers, and the candidate's chosen optional subject. Candidates who cleared the OCS Preliminary examination are eligible to appear in the Mains. The exam will be held in offline (descriptive/pen-and-paper) mode, in two shifts per exam day for most papers, at designated centres. OPSC will upload admit cards and detailed candidate instructions on its official website closer to the exam, typically about a week in advance. Candidates should regularly check the official OPSC portal for the exact admit card release date, exam-day guidelines, and any updates to the schedule. Aspirants are advised to begin preparation for the optional subject and General Studies papers early, given the compressed run-up between the schedule announcement and the exam dates.
