🏃 Constable: Physical Test Determines ENTIRE Merit
Unlike most police exams, Bihar Police Constable written exam is qualifying only (minimum 30%). The PET (Physical Efficiency Test) carries 100 marks and is the SOLE basis for the final merit list. Written exam scores are not added. Physical fitness is the #1 priority.
⚠️ SI: Only Mains Paper II (200 marks) Counts
For Bihar Police SI: Prelims is qualifying (30% min), Mains Paper I (Hindi) is qualifying, only Mains Paper II (200 marks, -0.2 negative) determines final rank. Paper II has -0.2 marks per wrong answer.
📋 Two Separate Boards: CSBC vs BPSSC
CSBC (Central Selection Board of Constables) conducts Constable recruitment. BPSSC (Bihar Police Sub-Ordinate Services Commission) conducts SI/Daroga recruitment. Different boards, different processes, different official websites.

Bihar Police tests GK, Hindi, English, Maths, Science and Social Science. SI Mains Paper II tests General Studies at graduation level. Bihar-specific GK is important throughout.
⚖️ Bihar Police Constable vs SI - Complete Comparison
Both have completely different merit systems. Constable merit = PET marks only. SI merit = Mains Paper II only. Understanding this determines your preparation strategy.
👮 Bihar Police Constable (CSBC) - Exam Pattern
Written exam is QUALIFYING ONLY. Score 30% to pass. The physical test (PET) carries 100 marks and is the sole basis for the final merit list and appointment.
📄 Written Exam - OMR Based (QUALIFYING ONLY)
100 MCQs - 100 marks - 2 hours - No negative marking - Min 30% required
+1 per correct. No negative marking. Minimum 30 marks (30%) required to qualify. Written exam marks NOT added to final merit. OMR sheet. Bilingual (Hindi and English). Content at Matriculation (Class 10) level.
🏃 Selection Process and Merit System
1Written Exam (Qualifying): Min 30% required. Marks NOT in merit.
2Physical Standards Test (PST): Height, chest (male), weight checks. Qualifying only.
3PET - Physical Efficiency Test (100 marks): Running, Shot Put, Long Jump. SOLE MERIT BASIS.
4Document Verification → Medical → Appointment
Key insight: Bihar Police Constable selection is primarily a physical competition. Two candidates with identical written scores are ranked entirely by PET performance. Written exam preparation needs only to clear the 30% qualifying mark - invest most time in physical training.
🏃 PET Marks Distribution and Physical Standards (Constable)
PET carries 100 marks and is the SOLE basis for final merit. Maximum marks per event determine your rank. Physical performance directly determines selection.
🏃 PET Events and Marks (Male)
Total: 80 marks for running + field events. Remaining 20 marks from sports participation or other criteria per notification. Check specific CSBC notification for exact marks per performance level.
📏 Physical Standard Test (PST)
PST is qualifying - no marks for PST. Failure to meet height/chest standards = disqualification. Always verify from specific CSBC notification as standards may vary by post category.
💡 PET Strategy for Constable
- Run 1 Mile (1.6 km) under 6 minutes = maximum 40 marks
- Every second above 6 minutes = lower marks tier
- Train for sub-6 minute mile: requires 4-5 months of dedicated training
- Shot put: build arm and shoulder strength through daily practice
- Long jump: practice approach run and take-off technique
- Physical training schedule: 2 rounds running daily (morning + evening), weekly speed trials
- Since PET is merit-deciding, maximise each event score - not just qualify
- Many candidates lose selection with good written scores but poor PET performance
🎖️ Bihar Police SI / Daroga (BPSSC) - Prelims and Mains Pattern
Three written stages: Prelims (qualifying) → Mains Paper I Hindi (qualifying) → Mains Paper II General Studies (200 marks, -0.2 negative, MERIT). Only Paper II score determines final rank.
📄 SI Prelims - Qualifying Only
100 MCQs - 100 marks - 2 hours - Min 30% required - Marks NOT in merit
Qualifying: 30% minimum. Marks not counted in merit. Shortlists candidates for Mains. Online CBT mode. Only GK tested in Prelims - not Hindi, Science or other subjects.

- Translation (English to Hindi)
Qualifying paper - marks not added to merit. Must score qualifying marks to be eligible for final merit based on Paper II. Failing this paper = eliminated regardless of Paper II performance.
📄 Mains Paper II - General Studies (MERIT DECIDING)
200 MCQs - 200 marks (2 marks each) - 2 hours - -0.2 negative marking - SOLE MERIT BASIS
+2 per correct. -0.2 per wrong (1/10 of 2 marks). 2 hours for 200 questions = 36 seconds per question average. Final merit is based 100% on Paper II scores. Bihar-specific GK content appears throughout all sections. Questions at graduation level.

✅ Eligibility Criteria
Constable needs 12th pass; SI needs graduation. Age limits and physical standards differ between the two posts.
💰 Salary, Pay Scale and Career
Bihar Police offers permanent state government service with 7th Pay Commission scales, DA, HRA and other benefits.
📈 Constable Career Path
Constable → Head Constable → ASI → Sub Inspector (via departmental exam after 8-10 years) → Inspector
📈 SI Career Path
Sub Inspector → Inspector → DSP (Deputy SP) → SP → SSP → DIG → IG → ADG → DGP
📈 Previous Year Cut-off Marks
Constable cut-off = PET marks (not written exam). SI cut-off = Mains Paper II marks.
🏃 Constable Cut-offs (PET out of 100)
| Category | PET Cut-off (approx) |
|---|---|
| General (Male) | 70 - 80+ |
| OBC (Male) | 65 - 75 |
| SC (Male) | 60 - 70 |
| General (Female) | 55 - 65 |
PET cut-offs indicate final selection marks. Maximum 40 marks from running alone - target sub-6 minute mile for 40 marks. Cut-offs vary by batch size and category distribution.
📝 SI Mains Paper II Cut-offs (out of 200)
| Category | Paper II Cut-off |
|---|---|
| General | 130 - 150 |
| OBC | 120 - 140 |
| SC | 108 - 128 |
| ST | 100 - 120 |
Indicative estimates. -0.2 negative marking means accuracy is crucial. At 2 marks per question, getting 70 correct with 10 wrong = 140 - 2 = 138 marks. Target 70%+ correct rate.
💡 Expert Preparation Tips
From our faculty who have guided thousands of Bihar Police Constable and SI selected candidates
1
For Constable: treat written exam as a formality, spend 70% of prep time on physical training - Bihar Police Constable's final merit is based 100% on PET scores. The written exam is qualifying only - you just need 30/100 (30%). This means a candidate who scores 95 in written but 55 in PET will rank below someone who scored 32 in written but 80 in PET. Strategic allocation: spend only 30% of your total preparation time on written exam content (enough to ensure clearing 30% comfortably with some safety margin). Spend 70% on physical training - specifically timed 1-mile runs to build speed, shot put technique practice, and long jump approach and takeoff drills. Build physical fitness as a primary goal; written exam content as secondary.
2
For SI: only Mains Paper II (200 marks) determines your rank - Prelims and Hindi paper are just gates to pass - Bihar Police SI's final merit is based 100% on Mains Paper II scores. Prelims (100 marks GK) is qualifying only at 30% minimum. Mains Paper I (Hindi, 100 marks) is qualifying only. This means: spend minimal time on Prelims (just clear 30%); spend adequate time on Hindi qualifying paper (clear qualifying marks, not aiming for max marks here); invest the vast majority of preparation time on Mains Paper II General Studies content - Bihar history, geography, polity, economy, science, current affairs at graduation level. Paper II has -0.2 negative marking so accuracy matters, but the primary goal is mastering the broad General Studies syllabus.
3
Bihar-specific GK is extensively tested - standard national GK books are insufficient for both Constable and SI - Both Bihar Police Constable GK section and SI Mains Paper II test Bihar-specific content extensively: Pataliputra as the ancient capital of Maurya Empire, Nalanda university, Bodh Gaya (Buddha's enlightenment), Vaishali as world's first republic, Champaran Satyagraha (Gandhi's first civil disobedience movement in Bihar 1917), Chhath Puja, Madhubani painting, Sonepur Mela, Kosi floods, Muzaffarpur lychee, Bhagalpur silk, Bihar polity (current CM/Governor, Vidhan Sabha seats), Bihar government schemes (Saat Nishchay, Mukhyamantri Gram Parivahan). Prepare dedicated Bihar GK notes using Bihar-specific preparation books or CSBC/BPSSC syllabus-aligned resources.
4
SI Mains Paper II -0.2 negative marking requires selective accuracy - not reckless volume - Mains Paper II has 200 questions in 2 hours (36 seconds per question average) with -0.2 per wrong answer. At 2 marks per correct and -0.2 per wrong: attempting 180 questions with 140 correct and 40 wrong gives 280 - 8 = 272 marks? No - total is 200 maximum (2 × 200 questions = 200 marks max, not 200 questions at 2 marks = 400 marks). Actually: 200 questions × 2 marks = 400 marks maximum, final score calculated from correct - 0.2×wrong. Target: 150+ correct with fewer than 20 wrong for a score of 300+ out of 400. Do not attempt uncertain questions where you cannot eliminate any option - the -0.2 penalty is 10% of the question value, which with 5-option guessing gives -0.2 + 0.4 expected = positive, but random 4-option guessing gives -0.2 + 0.5 expected = also positive. Use elimination strategy.
5
Constable 1-mile run training: build from couch to sub-6 minutes over 12-14 weeks - The 1-mile run in under 6 minutes is the highest-marks event in Bihar Police PET (40 marks maximum). Sub-6 minute mile requires a pace of under 3 minutes 45 seconds per kilometer - a standard that takes sustained training to achieve. Training protocol: Week 1-2: run 2-3 km daily at comfortable pace; Week 3-4: increase to 4-5 km daily; Week 5-8: include interval training (400m × 6 repeats with 90-second rest); Week 9-12: weekly timed mile trials, target sub-7 minutes first then push to sub-6.5 and finally sub-6; Week 13-14: race-specific pace training. Do NOT attempt speed training without aerobic base - risk of injury. Rest days are essential. Track weekly progress with a 1-mile time trial every Saturday.

CSBC and BPSSC are separate organisations - monitor both if you want maximum Bihar Police opportunities - CSBC (csbc.bih.nic.in) handles all Constable-level Bihar Police recruitment. BPSSC (bpssc.bihar.gov.in) handles Sub Inspector/Daroga, Sergeant and Jail Superintendent recruitment. They release notifications independently on different timelines. Many Bihar Police aspirants who register only on one portal miss notifications from the other. Register and set alerts on both websites. The preparation overlaps significantly - Bihar GK, Hindi grammar, General Science and Social Studies preparation covers both Constable written exam and SI Mains Paper II. If you are a 12th pass candidate currently preparing for Constable, also prepare for SI simultaneously if you are completing or have completed graduation - this gives you two simultaneous career opportunities from one preparation base.
❓ Frequently Asked Questions - Bihar Police 2025-26
Most searched questions about Bihar Police Constable and SI exam pattern, merit system and physical test answered
Bihar Police Constable has a uniquely physical-focused selection system. The written exam is qualifying only - you must score 30% (30 out of 100) to clear it, but your written marks have zero impact on your final rank. The Physical Efficiency Test (PET) - including running, shot put and long jump - carries 100 marks and is the sole basis for the final merit list and appointment. This is fundamentally different from UP Police (where written exam is the merit-deciding stage), SSC or banking exams, and even Bihar Police SI (where written exam determines merit). The rationale is that Bihar Police Constables perform physical law enforcement duties, so physical fitness is the primary selection criterion. In practice, this means a highly educated candidate with excellent academic knowledge but average physical fitness will rank below a candidate who just cleared the 30% written minimum but excels in running and field events.
Bihar Police SI selection has multiple written stages but only one determines final rank. The stages are: (1) Prelims - 100 MCQs, 100 marks, 2 hours, General Knowledge only, qualifying at 30% minimum, marks NOT counted in final merit. (2) Mains Paper I - General Hindi, 100 MCQs, 100 marks, 2 hours, qualifying only - marks not counted in merit. (3) Mains Paper II - General Studies, 200 MCQs, 400 marks maximum (2 marks each), 2 hours, -0.2 negative marking, **this is the SOLE basis for final merit list**. After Mains Paper II, candidates are shortlisted for: (4) Physical Efficiency Test (PET) - qualifying only for SI (unlike Constable where it decides merit). (5) Physical Standard Test (PST) - qualifying. (6) Document Verification. (7) Medical Examination. Final appointment as Sub Inspector. In summary: Prelims and Hindi Paper are just gates to pass; your entire selection depends on how you score in Mains Paper II General Studies.
The Bihar Police Constable written exam is at Matriculation (Class 10) level and covers Hindi, English, Mathematics, Social Science and General Science. Scoring 30% (30 out of 100) is the qualifying threshold, which is a relatively low bar for candidates who have completed 12th standard education. The exam tests fundamental school-level knowledge - basic arithmetic, elementary science, general awareness. A candidate who studied sincerely at the Class 10 level and reads newspapers regularly should clear 30% without extensive additional preparation. However, since the exam is competitive with lakhs of applicants, the actual pass percentage in written is relatively high (many candidates clear the written stage). The real competition begins at the PET physical stage. Recommended written exam preparation: 30-45 days of focused study covering Class 10 Social Science and Science textbooks, basic Hindi grammar, standard maths at Class 8-10 level, and daily newspaper reading for current affairs. This is sufficient to clear the qualifying threshold comfortably.
Yes - if you meet the eligibility criteria for both, you can apply for both simultaneously. Bihar Police Constable (CSBC) requires 12th pass and age 18-25 (General). Bihar Police SI (BPSSC) requires graduation and age 20-37 (General). If you are a graduate aged between 20-25 years, you technically meet both eligibility criteria. However, check each specific notification for any restriction on applying simultaneously. The preparation overlaps significantly: Bihar GK, Hindi grammar, General Science and Social Studies content is relevant for both Constable written exam and SI Mains preparation. Physical fitness training (running, field events) is relevant for both PET stages. However, the relative time investment differs dramatically: for Constable, prioritise physical training; for SI, prioritise Mains Paper II General Studies depth. A strategic approach is to target SI as the primary goal (higher pay, better career trajectory) while simultaneously maintaining physical fitness for the Constable PET in case SI written/physical clearance takes longer.
