BBOSE Class 12 provisional answer key 2026 has been released by the Bihar Board of Open Schooling and Examination, giving students an opportunity to review and challenge the objective answer key. This step is part of the transparency process in evaluation and allows candidates to raise concerns if they identify errors in the published responses. Candidates who appeared in the Class 12 exams are now able to access the provisional answer key and submit objections within the specified timeframe. This objection window is a crucial period for seeking corrections before the final evaluation is completed.
BBOSE Class 12 Objection Window Dates
The board has opened the objection window for the provisional answer key, enabling students to challenge any discrepancies found in the published answers for the June and December 2025 theory examinations. The objection submission period is open from January 7, 2026 and will close at 5:00 PM on January 9, 2026. Students must submit their objections within this window to ensure they are considered before finalising the answer key for evaluation.
How to Submit Objections Against the Answer Key
Candidates must carefully review the provisional answer key released by BBOSE and identify any questions where they believe the correct answer differs from the one published. The board has provided a formal objection mechanism to capture these concerns. Students are required to enter relevant details and justification for each objection they raise. Each submission will be reviewed by subject experts before any changes are made to the final answer key used for evaluation, ensuring fairness and accuracy in results.
Importance of the Objection Window
The objection window is an important phase in the board evaluation process that helps maintain the integrity of exam results. It allows candidates to participate actively in improving the accuracy of the answer key by pointing out possible mistakes or discrepancies. Once the objection window closes, the board will carefully review all submitted objections. Valid concerns may be incorporated into the revised answer key, which could influence students’ final scores and outcomes.
What Students Must Remember?
Students should ensure that they carefully check the details before submitting any objections. Submissions must be clear, relevant, and supported by appropriate reasoning, as only genuine challenges will be considered for revision. Candidates are advised to use the remaining time of the objection window before the January 9, 2026 deadline to complete their submissions and avoid any last-minute technical issues.
