OPSC AAO case studies

OPSC AAO · Put your knowledge to work in context.

The Assistant Agriculture Officer (AAO) is a Group-A recruitment conducted by the Odisha Public Service Commission (OPSC), the state body whose official portal is opsc.gov.in. Candidates apply online through the Commission's e-Chayan portal, and the credential suits agriculture graduates who want a state-government technical post in Odisha rather than a research or private-sector role. The selection process normally combines a written examination with document verification, and the written paper tests the agriculture domain: agronomy, soil science, plant protection, horticulture, agricultural extension, and allied farm-science topics. Because the Commission publishes the examination syllabus, previous question papers, recruitment calendar, and notifications on its Candidate's Corner, your first step is to read the current advertisement for the exact vacancy count, eligibility, age limit, and scheme of examination rather than relying on older figures. The OPSC AAO case studies are 5 cases and about 2,922 words.
