CBSE Class 11 Mathematics Syllabus 2023-24: CBSE is the national-level educational board of India which stands for Central Board of Secondary Education. In recent years CBSE has adapted many changes to its curriculum to ensure students don’t get overburdened with the extended syllabus. The aim of CBSE is to ensure quality education over quantity. Especially after the COVID-19 pandemic, the emphasis is on constraining the syllabus to the required limits of knowledge for students. CBSE has dropped many topics and even chapters from its syllabus and so is the effect on NCERT textbook content. 

If we talk about CBSE Class 11 Maths, many units have experienced drops in the topics whereas others have to drop chapters. To give you detailed information on what topics and chapters have been deleted from the CBSE Class 11 Mathematics syllabus 2023-24 we have framed this article. It will help you understand the new changes and the latest Mathematics syllabus for the academic year 2023-24 and 2024 final examinations.  Check the updated CBSE Class 11 Maths syllabus 2023-24 for better understanding.
