Mathematics is called as universal language. An equation or an expression written using mathematical notation can be read and understood by anyone across the globe. Thus having and firm foundation in mathematics will benefit student to a greater extent in developing problem-solving skills, mathematical modeling and also understanding allied subjects.

West Bengal board class 12 mathematics syllabus is prescribed by the West Bengal Council of Higher Secondary Education, commonly called as WBCHSE. The board was formed during the year 1975 and focuses on establishing quality higher secondary education in the state of West Bengal.

WBCHSE Class 12 Mathematics Syllabus enfolds diverse topics from Algebra, coordinate geometry, differential calculus, integral calculus, differential equations, application of calculus. The prime concepts studied here includes – Probability, principle mathematical induction, Binomial theorem for a positive integral index, infinite series, matrices and determinants, cones, parabola, elipse, hyperbola, differential calculus, indefinite integral, integration by parts, definite integral, differential equations, Tangent and normal, maxima and minima, determination of areas in simple cases, expression for velocity and acceleration etc.
