12 Maths

The CBSE class 12 syllabus for Mathematics has undergone constant changes, according to the needs of the society. Class 12 is a launch pad from where the students go either for higher academic education in Mathematics or for professional courses like engineering, physical and Bio science, commerce or computer applications. The present revised syllabus has been designed in accordance with National Curriculum Frame work 2005 and as per guidelines given in Focus Group on Teaching of Mathematics 2005 which is to meet the emerging needs of all categories of students. Emphasis has been laid on application of various concepts.

The curriculum is designed to focus on helping students acquire knowledge and critical understanding by means of basic concepts, terms, principles, symbols and mastery of underlying processes and skills, to develop a quantitative and a logical aptitude, acquaint students with different aspects of mathematics used in daily life, to develop an interest in students to study mathemati
cs as a discipline.
