BSEB Class 10 Maths Question Paper and PDF
The Bihar Board released the question paper PDF for the Class 10 Mathematics exam after the examination concluded. Students can download this PDF to review the types of questions asked, understand the paper pattern, and compare different sections of the syllabus covered. The question paper contains a mix of objective type, short-answer and long-answer questions that test candidates’ understanding in algebra, geometry, trigonometry and arithmetic based on the board syllabus.
BSEB Class 10 Answer Key: Unofficial and Official
Once the exam is over, several coaching institutes and educators release unofficial answer keys to help students estimate their probable scores before the board publishes the official answer key. The official answer key by BSEB is usually released later, often after the completion of all board examinations, allowing students to calculate their expected marks accurately.
How to Use the Answer Key?
- Download the correct answer key (unofficial first, official later).
- Match answers set-wise (A, B, C, D) from the question paper.
- Estimate marks based on correct responses — there is no negative marking in the BSEB Class 10 board exams.

To qualify for the board examinations, students must secure a minimum passing mark of 33 per cent in each subject, including Mathematics. Candidates scoring below this threshold may be declared as not qualified in that subject, requiring them to appear in compartment exams if offered by the board.
