Bihar Police Constable 2026 – Exam Pattern, Syllabus, Physical Standards & Complete Selection Guide

Here is the reality of Bihar Police Constable that most guides present backwards: the written exam is the easier gate, and the physical test is where selection actually happens. The written exam only requires 30% to qualify — but in the 2025 cycle, actual cut-offs for General male candidates went as high as 68 out of 100 because 5 times the vacancies were called for PET. The candidates who scored 68 and failed the physical test got nothing. The ones who scored 40 and excelled at PET got selected.

Understanding that structure changes how you prepare. Both the written exam and physical training must run in parallel from day one.

Recruitment Overview

Note: A new 2026 recruitment notification may be released by CSBC with updated vacancies. Always verify current vacancy numbers at csbc.bihar.gov.in before applying.

Selection — Three Stages, One That Decides Your Rank

The final merit list is based entirely on PET performance — not written exam marks. The written exam is a gate. PET is the competition.askfilo+1

What this means in practice: a candidate who scores 70 in the written exam and performs poorly in PET will rank below a candidate who scored 35 in the written exam and topped the PET scoring. The written exam decides who gets through the gate; PET decides who gets the job.

Written Exam Pattern

On no negative marking: Since there is zero penalty for wrong answers, every single question must be attempted — even if you have to guess. Leaving a question blank when there is no negative marking is giving away a free mark. This is a preparation and exam strategy point that directly affects your score.

On the 30% qualifying mark vs actual cut-off: The 30% minimum is a floor, not a target. In the 2025 cycle, CSBC shortlisted approximately 5 times the vacancy count for PET — meaning the actual written cut-off for General male candidates was 68 out of 100. Scoring 30% qualifies you in theory; you need 60–70% to realistically remain in PET contention.

Written Exam — Subject Breakdown

All subjects are tested at Class 10 (Matric) level — NCERT Class 9 and 10 textbooks cover the vast majority of the written exam syllabus.careerpower+1

Subject 1 — General Knowledge and Current Affairs (25 Questions)

Physical Standard Test (PST)

PST is measured before PET begins — candidates who do not meet height and chest standards are eliminated before PET events start:pw+2

Physical Efficiency Test (PET) — The Merit-Forming Stage

PET is where your selection rank is built. The events are scored — each event carries marks, and those marks form your PET score which decides your final rank. It is not simply pass/fail thresholds.

PET Events and Marks (Male):

Scoring breakdown within each event (Male):

Shot Put (16 lb):

• 16–17 feet → 9 marks | 17–18 feet → 13 marks | 18–19 feet → 17 marks | 19–20 feet → 21 marks | 20+ feet → 25 marks | Under 16 feet → Disqualified

High Jump:

• 4 feet → 13 marks | 4 feet 4 inches → 17 marks | 4 feet 8 inches → 21 marks | 5 feet or more → 25 marks | Under 4 feet → Disqualified

PET Events (Female):

Understanding that PET is scored — not just pass/fail — fundamentally changes your preparation approach. You cannot simply clear the minimums and expect selection. You need to exceed the minimum thresholds on every event to accumulate competitive marks. The candidate who throws 20+ feet in shot put (25 marks) has a decisive advantage over one who throws exactly 16 feet (9 marks) — even if both “passed.”

Physical Training Guide

Start physical training on the same day you begin written exam preparation — not after the written result. Six months of progressive training separates PET toppers from PET failures.

Running (1 mile / 1 km):
Start at your natural comfortable pace and build weekly. Use interval training — alternate between 200m fast and 200m slow — to improve pace. Target being able to complete the run in well under the minimum time to build a genuine buffer.

High Jump:
Approach, takeoff foot, and clearance technique matter as much as raw leg strength. Practice the run-up approach and takeoff consistently — poor technique eliminates candidates who have adequate jumping ability.

Long Jump:
Approach run speed, takeoff angle, and landing position all affect distance. Practice the full run-up and consistent takeoff foot placement.

Shot Put:
Grip, stance, push angle, and follow-through technique are separate skills from raw strength. Practice with the correct weight shot (16 lb for male, 12 lb for female) from the beginning — not with a lighter substitute.

Document Verification

Documents required:

• Class 10 (Matric) certificate and marksheet — age and qualification proof

• Caste certificate — Bihar state format (not central government format, unlike SSC/UPSC)

• OBC certificate — current financial year (expired = rejected)

• EWS certificate — current financial year

• Bihar domicile/residence certificate — mandatory, Bihar domicile-restricted post

• Aadhaar Card

• Character certificate

• Passport photographs (6–8 copies)

• Ex-serviceman/PwD certificate if applicable

Most common DV rejection reasons:

• OBC certificate from wrong year

• Domicile certificate not issued by Bihar authority — this post is strictly Bihar-domicile restricted

• Name mismatch between application and Class 10 certificate

Medical Standards

Age Relaxation

6-Month Preparation Plan

Months 1–2 — Written Exam Foundation
NCERT Class 9–10 Science (Physics and Chemistry) — read all chapters, note formulas and definitions. NCERT Class 6–10 Maths — complete Percentage, Profit/Loss, SI/CI, Mensuration, Geometry. Lucent’s General Knowledge with strong Bihar-specific preparation. Start a Bihar-focused monthly current affairs magazine. Physical training begins: 1 km daily run, basic jump and shot put practice.

Months 3–4 — Section Practice
25 Physics questions daily from previous Bihar Police papers. 25 Chemistry questions daily. 20 Maths questions daily — priority on the five high-weightage clusters. GK: 20 questions daily alternating Bihar GK and national GK. Since there is no negative marking, attempt every question in practice — build the discipline of zero blanks. Physical training: build run to near-target pace; consistent high jump and long jump technique sessions; shot put practice with correct weight.

Month 5 — Full Paper Practice
Two complete 100-question mock tests per week, OMR-style, 120-minute limit. Target completion in under 90 minutes to allow review. No question left blank — ever. Physical training: run at target speed 4 times per week; PET event practice 3 times per week.

Month 6 — PET Preparation and Final Revision
Written exam: current affairs and static GK revision only — no new topics. PET focus: exceed minimum thresholds on every event — the shot put, high jump, and long jump scoring bands mean every extra foot or inch directly adds marks to your selection rank. Begin taper training in final 2 weeks — maintain fitness without overtraining before PET day.
