The OPSC ASO written exam is on 17 January 2027. Counting from 6 November, that is about 72 days. This plan splits them into four phases: topic-by-topic learning until 7 December, one round of subject-wise sectional tests from 8 to 14 December, full-length mocks from 15 December, and a final week of previous year papers and revision. Every test on this site is free and needs no login.

Phase 28 – 14 DecSubject-wise sectional tests

Phase 315 Dec – 10 Jan14 full-length mocks

Phase 411 – 16 JanPYQ mocks and revision

How to use this plan

Phase 1 — Daily topics (6 November – 7 December)

The topics follow the ASO syllabus and the last three ASO papers (2018-19, 2021-22 and 2025-26). Current affairs is the biggest single block in Paper I (20–29 questions a year), so from Day 3 every General Studies test carries five current affairs questions, alongside Polity, Modern History, Geography, Defence and Odisha. In Paper II, probability alone had 9–10 questions in 2018-19 and 2021-22, so it gets two days, with statistics, equations and progressions a day each; Reasoning covers the verbal and non-verbal mix that has stayed at about 30 : 20. English is mostly grammar and usage, and Odia covers every chapter the last three papers drew on, in the order of the standard grammar book: spelling, synonyms and antonyms, parts of speech, verbs (କ୍ରିୟା, four days), case, word formation, sentences and sentence transformation, and a passage.

Frequently asked questions

Is the OPSC ASO 70-day plan free?

Yes. The plan, the daily tests (30 questions per subject, 150 a day), the sectional tests and the full-length mocks are free and need no login.

When should I start the ASO 70-day plan?

Day 1 is Friday, 6 November 2026. If you start later, follow the day you are on and finish the missed days on Sundays after the weekly test.

How many full-length mocks are there before the ASO exam?

Fourteen full mocks between 15 December and 10 January, followed by the 2018-19, 2021-22 and 2025-26 previous year papers as mocks in the final week.

Which topics does the ASO plan focus on?

The plan follows the ASO syllabus and the last three papers. Current affairs, Polity, Modern History, Geography, Defence and Odisha lead General Studies; probability, statistics, equations and progressions get their own days in Quant; English is mostly grammar and usage; Odia covers spelling, synonyms, antonyms and grammar.

Does the plan cover the computer skill test?
