Syllabus update and verification

The Bihar School Examination Board's available Class 9 Mathematics syllabus is presented in a combined syllabus document. Its monthly progress chart covers six units and 15 chapters, with a total allocation of 100 marks.

The latest independently verified official PDF is labelled for the 2023-24 and 2024-25 sessions. Reports published on 11 November 2026 say the syllabus has not changed for 2026-27, but a separate Mathematics PDF dated 2026-27 has not been independently confirmed. Students should check with their schools before treating the older document as their final examination reference.

Units and topics

The available chart covers Number Systems, Algebra, Coordinate Geometry, Geometry, Mensuration, and Statistics and Probability. Algebra is allocated 25 marks, while Geometry has the highest allocation. These figures come from the older chart and are not a newly confirmed 2026-27 examination blueprint.

Number Systems includes real numbers, decimal expansions and exponents. Algebra covers polynomials and linear equations in two variables. Coordinate Geometry introduces axes, quadrants and plotting points.

Geometry includes lines and angles, triangles, quadrilaterals, circles and constructions. Mensuration includes Heron's Formula and surface areas and volumes. Statistics and Probability covers data presentation, measures of central tendency and introductory probability.
