The admit card for BPSSC SI Mains 2026 dropped on 13 May 2026. If you're holding that admit card, you've already beaten thousands in the prelims — that's real. Now comes the mains, scheduled for 27 May 2026.
Let's be straight: previous year papers for BPSSC SI Mains aren't easily available anywhere online. What IS available — and what actually helps in the final 14 days — is knowing exactly which topics Bihar Police examines, what the question weightage looks like, and how to stop wasting time on low-value areas. That's what this article covers.
BPSSC SI Mains 2026 — Exam Pattern
The mains is a written examination conducted in offline (pen and paper) mode. It tests candidates across Hindi language proficiency and General Studies. Always cross-check the final pattern on your admit card or from bpssc.bih.nic.in.
| Stage | Type | Marks | Duration |
|---|---|---|---|
| Prelims | Objective MCQ | 100 marks | 2 hours |
| Mains | Written Exam | 200 marks | As per admit card |
| Physical Test | PET/PST (qualifying) | — | — |
| Medical | Qualifying | — | — |
The Mains examination covers two primary sections:
| Section | Topics Covered | Weightage |
|---|---|---|
| General Hindi | Grammar, comprehension, essay, letter writing | High |
| General Studies | Bihar GK, Indian Polity, History, Geography, Science | High |
Unlike prelims, the mains is written format — not MCQ. Your answers must be structured in paragraphs for essay/long-answer questions. Marks are given for content + presentation. No negative marking in mains.
Section 1 — General Hindi: What Bihar Police Asks
Bihar Police SI Hindi section is BSEB Intermediate level. It's not UPSC-level Sanskrit or complex compound sentences — it's practical, functional Hindi. Here's where marks actually come from:
| Topic | Approx Weight | Difficulty |
|---|---|---|
| व्याकरण (Grammar) — संज्ञा, सर्वनाम, विशेषण, क्रिया | High | Easy-Medium |
| पर्यायवाची / विलोम (Synonyms / Antonyms) | High | Easy |
| मुहावरे और लोकोक्तियाँ (Idioms & Proverbs) | Medium | Medium |
| अपठित गद्यांश (Unseen Passage) | High | Medium |
| पत्र लेखन (Letter Writing) | Medium | Easy-Medium |
| निबंध लेखन (Essay Writing) | High | Medium |
Top tip for Hindi: In the essay section, write about topics you know well — crime prevention, women's safety in Bihar, rural development. These match Bihar Police's work directly. Don't pick abstract topics if you have a choice.
Section 2 — General Studies: Bihar-First Approach
This is where most candidates lose marks — they study Indian GK broadly and ignore Bihar-specific content. Bihar Police values candidates who know their state. Here's the actual topic distribution from multiple Bihar Police examinations:
| Sub-Topic | Coverage | Pro tip |
|---|---|---|
| Bihar Geography | Districts, rivers, borders, divisions | Know all 9 divisions + 38 districts |
| Bihar History | Pataliputra, Maurya, Sher Shah, 1857 revolt in Bihar | Patna = Pataliputra = Azimabad |
| Bihar Economy | Agriculture (rice, wheat, maize, makhana), industries | Makhana = 80% of world supply from Bihar |
| Indian Constitution | FRs, DPSPs, IPC 302/307/354 (police context) | Know police-related IPC sections |
| Science & Tech | Class 10 physics, chemistry, biology basics | No advanced concepts needed |
| Current Affairs | Bihar govt schemes, CM/Governor, national events (last 6 months) | Bihar Mukhyamantri + state budget key |
Bihar Police SI GS paper consistently includes 1-2 questions on Bihar government's crime/law schemes — Mukhyamantri Krishi Ashirwad Yojana, Mukhyamantri Balika Cycle Yojana, MNREGA in Bihar. These are free marks. Learn them.

What No Other Site Will Tell You About BPSSC SI Mains
Here's the honest part. Most coaching sites give you a Bihar Police GK PDF and call it preparation. What they don't say:
- The essay section has fixed theme types. Bihar Police essays almost always fall into: (1) social issues in Bihar, (2) law & order topics, (3) women's safety/empowerment, or (4) rural Bihar development. Prepare 2 strong essays in each category. You don't need to memorize 50 essay topics.
- Letter writing is Hindi, not formal English style. Many candidates write letter formats from English patterns — wrong. BPSSC expects Hindi sarkari patra (official letter format) with seva mein opening, vinay nivedan content, and bhavanukul closing.
- Bihar Police is not looking for rank-1 brilliance in mains. It's a qualifying exam for the PT round. Know the pattern, attempt all questions, write legibly. The physical test is where many candidates actually fall out — don't neglect running/endurance in these final 14 days.
