The Class 12 Mathematics examination for Science and Commerce streams is conducted by the Bihar School Examination Board (BSEB). The Mathematics exam is very high-scoring but also involves a lot of concepts that need to be understood, and scoring well in the Mathematics examination helps improve the overall percentage. Furthermore, scoring well in Mathematics helps students qualify for top engineering colleges, B. Sc courses, competitive examinations, and scholarship programs.
Students preparing for this exam should understand what the exam dates are, what the syllabus is, what the pattern of the paper is, what weightage needs to be provided to each chapter, and what has been the past year's trend. In this blog, we provide a complete guide to the 2026 BSEB Class 12 Mathematics exam that students can use to plan, practice, and score well.
The BSEB Intermediate Maths Exam assesses students’ conceptual understanding, numerical ability, and ability to use formulas in different contexts. The subject syllabus includes key units, such as Algebra, Calculus, Probability, Vectors, 3D Geometry, and Linear Programming, that are required for other competitive exams, including JEE, NDA, CUET, and other state-level entrance exams.
Each year, the paper will have a balanced mix of tasks that have short, medium, and long mark weights to them. Students that put in consistent effort and practice, will easily be able to achieve 85-90+ in Maths.
Key Highlights
BSEB Intermediate Exam 2026 will, as per yearly schedule, likely have contents in February 2026. The detailed date sheet will be available in December 2025 on the official website (biharboardonline.bihar.gov.in ). Once the timetable is released, students should revise according to the exam sequence and prioritize high-weightage chapters.
Students can plan their preparation, and since they will understand themselves which topics will or will not be useful, this will save them time. The Maths syllabus is designed to develop students' logical reasoning, problem solving ability, and mathematical thinking.
BSEB Class 12 Maths Syllabus 2026 — Unit List
What Students Should Focus On: Calculus and Algebra form nearly 50–55% of the paper, so students must practice them thoroughly through textbook exercises, PYQs, and sample tests.
The Bihar Board follows its standard pattern every year with a mix of Objective + Subjective questions.
Important:
Bihar Board strictly follows step-wise marking, so neatness and proper method matter significantly.
Based on analysis of previous year BSEB papers, here is an estimated distribution:
Calculus, Algebra, and Probability should be revised at least 3–4 times before the exam.
Practicing previous year question papers helps students:
Solving last 5–10 years papers gives the best possible understanding of the exam. Many question patterns, formulas, and numerical types repeat every year with slight changes.Try completing each PYQ in a 3-hour timer to simulate the actual exam.
Benefits of PYQ Practice
Familiarity with exam format
Realistic time management
Boosts confidence
Reduces silly mistakes
Helps master high-weightage topics
Improves calculation speed
Identifies weak areas
