BBOSE Opens Answer Key Objection Window for 12th Theory Exams 2025
BBOSE 12th Answer Key Objection Window Open Jan 7-9

The Bihar Open Schooling and Examination Board (BBOSE) has initiated a crucial step for ensuring transparency in the evaluation of its Higher Secondary (12th) theory examinations. The board has officially opened a window for candidates and the public to raise objections against the provisional answer keys for objective-type questions.

Key Details of the Objection Window

This process is applicable for the theory papers of both the First and Second Higher Secondary Examinations conducted in June 2025 and December 2025. The facility covers all theoretical subjects where OMR-based answer sheets were used. The objection window is open for a limited period from January 7, 2026, to January 9, 2026, until 5:00 PM. The board has made it clear that no objections will be entertained after this deadline through any means.

The answer keys, prepared by subject experts, have been uploaded on the board's official websites for public scrutiny. This move is aimed at promoting a fair assessment process and allowing candidates to point out any perceived discrepancies before the final results are prepared.

How to Submit an Objection Online

Candidates wishing to challenge an answer must follow a specific online procedure:

  1. Visit the official portal: http://objmatric.biharboardonline.com/ and click on the link for "Objection regarding BBOSE."
  2. Log in using the required exam credentials and select the relevant Higher Secondary subject and paper.
  3. Review the published answer key and select the specific objective question for which you wish to raise an objection.
  4. Fill out the online objection form, providing your suggested answer along with a supporting explanation.
  5. Double-check all entered information and submit the form before the deadline of January 9, 5:00 PM.

The answer keys are also available for reference on the main board website at https://biharboardonline.com.

Expert Review and Final Evaluation

Once the objection window closes, an expert committee constituted by the BBOSE will review all valid challenges. The OMR sheets will then be evaluated based on the revised, final answer keys that emerge from this review process. This step is integral to maintaining the accuracy and uniformity of marks awarded for objective questions across both examination sessions, in strict adherence to the board's notified procedures.

The official notice for this process has been issued by the Controller of Examinations (Higher Secondary), BBOSE, under Advertisement No. PR 08/2026. This structured objection mechanism underscores the board's commitment to fair and transparent evaluation for all its candidates.
