Each year, lakhs of aspirants across Bihar — and many from outside it — sit for the Combined Competitive Examination (CCE) of the Bihar Public Service Commission (BPSC). It recruits officers to some of the most important posts in the state: Sub-Divisional Officer / Senior Deputy Collector, Deputy Superintendent of Police, Revenue Officer, Block Development Officer, Supply Inspector, Rural Development Officer and many others.
The examination has changed in recent cycles. If you are preparing from older material or older advice, the first thing to do is understand the current pattern.
The three stages
| Stage | Nature | Counts for final merit? |
|---|---|---|
| Preliminary | Objective, one paper | No — screening only |
| Main | Descriptive (plus a qualifying objective Optional) | Yes — the core of merit |
| Interview | Personality test | Yes |
Stage 1: Preliminary examination
| Feature | Detail |
|---|---|
| Paper | General Studies (single paper) |
| Questions | 150 multiple-choice questions |
| Marks | 150 |
| Duration | 2 hours |
| Negative marking | Yes — a fraction of a mark is deducted for each wrong answer |
Unlike UPSC and MPSC, BPSC Prelims has no separate CSAT paper. Mental ability questions are included within the General Studies paper.
The Prelims covers:
- general science;
- current events of national and international importance;
- history of India, with salient features of the history of Bihar;
- general geography, and the geography of Bihar (including its major river systems);
- Indian polity and economy, including post-independence changes in Bihar's economy;
- the Indian national movement and Bihar's role in it;
- general mental ability.
Stage 2: the Main examination
| Paper | Subject | Marks | Nature |
|---|---|---|---|
| 1 | General Hindi | 100 | Qualifying — minimum 30 per cent |
| 2 | General Studies Paper I | 300 | Counts for merit |
| 3 | General Studies Paper II | 300 | Counts for merit |
| 4 | Essay | 300 | Counts for merit |
| 5 | Optional subject | 100 | Qualifying, objective (MCQ) |
So the merit-bearing written papers total 900 marks: GS I, GS II and the Essay.
What the GS papers cover
| Paper | Main areas |
|---|---|
| GS I | Modern history of India and Indian culture; current events of national and international importance; statistical analysis, graphs and diagrams |
| GS II | Indian polity; Indian economy and geography of India; the role and impact of science and technology in the development of India — with Bihar-specific dimensions throughout |
The Essay paper
The Essay paper is divided into three sections, and candidates write one essay from each. It carries as much weight as a GS paper — and because it rewards your own thinking, it is often where rank differences are made. See our guide to the BPSC Essay paper.
The Optional paper
The Optional is objective and qualifying: you must reach the minimum mark, but it does not add to your merit. That is a big change from the older pattern, where the Optional was a large, descriptive, merit-bearing component.
Stage 3: the interview
The interview carries 120 marks. The final merit list is based on:
| Component | Marks |
|---|---|
| Mains (GS I + GS II + Essay) | 900 |
| Interview | 120 |
| Total | 1,020 |
Language of the examination
Answers may be written in Hindi or English. A large share of BPSC candidates write in Hindi. Choose the medium in which you can write fastest and most precisely — see our guide on choosing the medium.
Eligibility basics
- Education: graduation from a recognised university.
- Age: minimum and maximum limits vary by category and post, with relaxations for reserved categories and women as per state rules.
- Domicile: some reservations and relaxations apply only to residents of Bihar.
Always check the eligibility clauses in the current notification — especially for age relaxations and physical standards for police posts.
What the pattern means for your preparation
- General Studies is king. Two GS papers and the Essay carry all written merit.
- The Essay deserves serious practice — it is worth as much as a GS paper.
- Bihar-specific content runs through every paper — history, geography, economy, polity and current affairs.
- Do not neglect the qualifying papers. General Hindi (30 per cent) and the Optional must both be cleared.
- Data and statistics in GS I reward practice with graphs, tables and basic calculations.
