OPSC OCS Prelims syllabus

Optional subject papers

Candidates choose one optional subject from the list notified by OPSC and sit two papers in that subject. The available list has included disciplines across humanities, social sciences, sciences, engineering and literature. Examples include Agriculture, Anthropology, Geography, History, Law, Political Science and International Relations, Public Administration, Sociology, Mathematics, and Odia or other listed language literatures.

Confirm the current subject list and detailed paper syllabus in the official document. Compare the syllabus, your prior familiarity, available study resources and the time you can commit before choosing an optional.

Personality Test

The Personality Test assesses a candidate’s suitability for public responsibilities. Preparation should help you discuss your academic and personal background, Odisha and its current issues, public policy, and matters of contemporary importance with clarity. The interview is not a substitute for the written syllabus; it is the final stage of the selection process.
