The Bihar School Examination Board (BSEB) released the answer key for the 2025 Class 10 Matric Compartment and Special Examinations, providing students an opportunity to evaluate their performance in these supplementary exams. This answer key, covering objective questions across subjects like Mathematics, Science, Social Science, Hindi, and English, is accessible online through the official BSEB website, secondary.biharboardonline.com.
