The Bihar Board of Open Schooling and Examination (BBOSE) has opened its provisional answer key objection window for Class 12th Theory Exams. This process began on January 7, 2026 . Students who appeared for the BBOSE First and Second Higher Secondary (12th) theoretical examinations can now submit their challenges. All objections must be filed online via the official website, bboseonline.com .
Understanding Provisional Answer Keys
A provisional answer key is an initial set of correct answers released by the examination board. It allows students to estimate their scores before final results. However, errors can sometimes occur in these initial keys. The objection window provides a crucial mechanism for students to report any discrepancies they find. This ensures the accuracy of the final evaluation.
Eligible Examinations and Questions
The current objection facility specifically addresses examinations held in 2025 . It applies to candidates who wrote the BBOSE First Higher Secondary (12th) theoretical examination in June 2025 . It also includes students who took the Second Higher Secondary (12th) theoretical examination in December 2025 . This window is exclusively for challenging answers to objective questions presented in these exams. Subjective answers are not part of this review process.
The Importance of Objection Submission
Submitting a valid objection is important for examination fairness. If a student identifies an incorrect answer in the provisional key, challenging it can lead to a correction. A corrected answer benefits all students who selected the correct option for that question. This process directly impacts individual scores and the overall integrity of the examination results. Students should carefully review their answer sheets against the provisional key.
Step-by-Step Guide to Raise Objections Online
Students must navigate to the official BBOSE website: bboseonline.com . Upon reaching the homepage, locate the dedicated link for ‘Class 12th Answer Key Objections’. Clicking this link will direct users to the objection portal. Candidates typically need to log in using their roll number or application ID. They will then access their respective provisional answer keys.
Once logged in, students can view the answer key for their specific examination. They should compare it with their marked responses. If a student finds a discrepancy for an objective question, they can select it for objection. The portal will prompt them to provide a detailed justification or supporting reference for their challenge. Carefully submit all required information before the deadline to ensure the objection is considered.
What Happens After Submission
After the objection window closes, BBOSE subject experts will review all submitted challenges. They will examine the supporting evidence provided by students. If an objection is found valid, BBOSE will update the provisional answer key. This revised key then becomes the final answer key. All results will be calculated based on this final, corrected answer key. The decision of the expert committee regarding the objections is final.
Official Confirmation from BSEB
The Bihar School Examination Board (BSEB) officially announced the opening of this objection window. The announcement was made through BSEB’s official social media channels. The communication specifically highlighted the process for objective questions from the June 2025 and December 2025 Higher Secondary theoretical exams. This confirms the legitimacy and scope of the ongoing objection period.
