Bihar Police SI

The Bihar Police SI Syllabus 2026 is divided into a Preliminary Written Examination and a two-paper Main Written Examination. Candidates who qualify the written stages are called for the Physical Efficiency Test.

Under BPSSC Advertisement No. 05/2025, the Preliminary Examination contains 100 multiple-choice questions for 200 marks, while the Main Examination consists of General Hindi and General Studies papers carrying 200 marks each. The General Hindi paper is qualifying and its marks are not included in final merit.

Bihar Police SI Exam Pattern 2026 Overview

BPSSC conducts the written examination in objective multiple-choice format.

Bihar Police SI Prelims Exam Pattern 2026

The Preliminary Examination is the first screening stage.

BPSSC states that candidates scoring less than 30% in the Preliminary Examination are declared unsuccessful for the Main Examination.

However, merely crossing 60 marks does not guarantee qualification for Mains.

BPSSC shortlists candidates in merit order and category-wise, normally up to approximately 20 times the number of available vacancies, subject to the availability of eligible candidates.

Bihar Police SI Prelims Syllabus 2026

The official Preliminary syllabus consists of General Knowledge and Current Events.

BPSSC does not prescribe a fixed number of questions from individual General Knowledge areas. A practical preparation syllabus can be divided into the following areas.

Bihar Police SI Negative Marking 2026

This is a fixed deduction of 0.2 mark for a wrong response.

This means the negative penalty is relatively small compared with the 2 marks awarded for a correct answer, but random guessing can still reduce the final score when repeated across many questions.

Are Prelims Marks Added to Final Merit?

Final merit is prepared on the basis of the Main Written Examination, while General Hindi is explicitly excluded from merit calculation.

Therefore, the merit-relevant scoring component is effectively Mains Paper II.

Prelims should be treated as an important screening hurdle, but candidates ultimately need a strong Mains General Studies score for final ranking.

How Many Candidates Qualify Prelims for Mains?

BPSSC normally shortlists candidates up to approximately:

For 1,799 vacancies, this framework can produce a large Mains candidate pool, although the actual number can vary according to BPSSC's rules and availability of qualifying candidates.

The Commission can reduce the ratio if sufficient eligible candidates are unavailable.

How Many Candidates Are Called for the Physical Test?

On the basis of the Main Written Examination, candidates are shortlisted category-wise at approximately:

The physical stage is qualifying.

Candidates therefore need both:

• A sufficiently strong Mains score to be shortlisted
• Successful completion of the physical requirements

Bihar Police SI Final Merit

BPSSC's rules state that the final category-wise merit list is prepared on the basis of marks obtained in the Main Written Examination.

General Hindi marks are excluded from merit.

The Physical Efficiency Test is qualifying only.

Bihar Police SI Minimum Final Qualifying Marks

The applicable rules prescribe minimum qualifying percentages for final merit consideration:

These thresholds are established in the Bihar Police recruitment rules.

Prelims vs Mains: What Changes?

The difficulty also changes.

Prelims rewards broad awareness and quick recall, while Mains requires wider static-subject coverage across History, Geography, Civics, Science, Mathematics and Mental Ability.

Does Bihar Police SI Have a Separate Bihar GK Section?

The official domains are General Studies, General Science, Civics, Indian History, Geography of India, Mathematics and Mental Ability.

Similarly, Prelims is officially described as General Knowledge and Current Events.

However, Bihar-specific questions can naturally fall within General Knowledge, General Studies, History, Geography and Current Affairs.

Candidates should therefore prepare Bihar GK without assuming that it will appear as a separately labelled section.

Is There a Fixed Subject-Wise Weightage in Mains Paper II?

BPSSC specifies the subjects but not a compulsory number of questions for:

• History
• Geography
• Science
• Civics
• Mathematics
• Mental Ability

Therefore, claims such as “exactly 20 History questions” or “exactly 10 Maths questions” should not be treated as official unless BPSSC issues a separate notice providing such distribution.

Current Status of Bihar Police SI Mains 2026

BPSSC's official website records that the Main Written Examination conducted earlier under Advertisement No. 05/2025 was cancelled through a notice dated 23 September 2026.

As of 3 October 2026, a fresh Mains examination date has not been shown on the official BPSSC notices page.
