CBSE Class 11 Mathematics Syllabus 2018 – 2019

New CBSE Class 11 Maths Syllabus for academic session 2018 – 2019 is available here. The Syllabus in the subject of Mathematics has undergone changes from time to time in accordance with growth of the subject and emerging needs of the society.

Senior Secondary stage (or Class 11 and Class 12) is a launching stage from where the students go either for higher academic education in Mathematics or for professional courses like Engineering, Physical and Bioscience, Commerce or Computer Applications.

The present revised syllabus has been designed in accordance with National Curriculum Framework 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.

Motivating the topics from real life situations and other subject areas, greater emphasis has been laid on the application of various concepts.

In this syllabus, student will get complete information about the course structure, paper pattern, prescribed textbooks etc.
