How to Calculate Your Score Using the Bihar Board 10th Answer Key 2026

The Bihar Board 10th paper is divided into two sections: Section A (Objective / MCQ) and Section B (Descriptive). The answer key covers only Section A. To estimate your objective-section score, you need your downloaded OMR response sheet and the corresponding subject-wise answer key.

• Download the official answer key PDF for your subject(s) from biharboardonline.bihar.gov.in.
• Download your individual OMR response sheet from the same portal (login required).
• Compare each question — add +1 mark for every question where your answer matches the answer key.
• Bihar Board 10th does NOT have negative marking — an incorrect response does not deduct any marks from your score.
• Unanswered questions (blanks on OMR) also carry zero marks.
• Repeat this process for each subject you appeared in during the compartment examination.
• Add your estimated objective-section score to your expected descriptive-section score for a full subject estimate.

Note: Only the official Bihar Board 10th Result 2026 (marksheet) contains your verified final score. The self-calculation method is an estimate for objective questions only.

Bihar Board 10th Marks vs Division 2026

Bihar Board 10th results are not ranked on a merit list in the same way as national entrance exams. Instead, students are awarded divisions based on their aggregate percentage across all subjects. The table below shows how marks correspond to divisions, helping you gauge your expected standing.

Note: For the Compartment Exam, the focus is on clearing individual failed subjects — a student who passes the compartment subject is treated as having passed the full Bihar Board 10th examination. The division calculation applies to the aggregate marks across all compulsory subjects.
