CSBC Bihar Police Constable Answer Key 2026

About This Answer Key

The Central Selection Board of Constable (CSBC), Bihar administers the written assessment system for hiring 83 Special Branch Constable positions under Advertisement No. 01/2026. Reviewing the answer framework helps candidates evaluate performance objectivity and project preliminary outcomes well before final result tabs open up officially.

A response sheet breakdown ensures transparency throughout the written phase. For this cycle, CSBC introduces a structured evaluation format across two distinct papers organized back-to-back in a single examination setting. Candidates have been given the specific privilege to carry a verified duplicate copy of their marked OMR solution worksheet for accurate post-exam assessments.

The objection and verification window operates as an administrative safety guard. It allows candidates to point out discrepancy items or key inaccuracies against published provisional drafts. Authentic proofs matching up to standardized reference literature must support each challenge to secure consideration by the evaluation review committees.

How to Calculate Expected Marks

Candidates can accurately calculate their estimated scores using the official testing matrix parameters defined in the recruitment advertisement:

• The test comprises 2 papers with each containing 100 multiple-choice questions.
• Every accurate answer rewards a value of +1 Mark.
• A definite negative grading system applies: every incorrect response incurs a deduction of -0.25 Marks.
• Use the formulation: Total Score = (Total Correct Items × 1) - (Total Incorrect Items × 0.25).
• Cross-verify your answers against the third carbonless OMR sheet copy retained from your testing venue.

Important Instructions

• OMR Carbon Backup: The OMR response sheet is generated in three parts. The original and second layers remain inside administrative care, while the third carbonless sheet is given directly to the candidate for personal analysis.
• Booklet Restrictions: Candidates are strictly forbidden from taking the original printed Question Booklet outside the testing hall boundaries.
• Biometric Protocols: Separate biometric identification and physical logs are registered independently for Paper 1 and Paper 2 stages.
• Late Submissions: Any grievance or option correction inputs filed after the scheduled objection close date will not be entertained.
• Disqualification Risks: Erroneous entries regarding Roll Numbers or Question Booklet numbers on the OMR system invalidate sheet scanning processes automatically.
