# CBSE Class 12 Mathematics Syllabus 2020-21 – Chapters, Topics, Weightage

CBSE Class 12 Mathematics Syllabus 2020-21 – Chapters, Topics are available here in this article. This information design is completely similar to the Central Board Of Secondary Education. CBSE Class 12 Mathematics Syllabus PDF is also available in this article. Check once in this article (सीबीएसई कक्षा 12 गणित का सिलेबस) and refer your regulation syllabus after that we start the examination preparation immediately. CBSE (Central Board Of Secondary Education) changes the syllabus curriculum year to year. That may know the CBSE  Class 11 Mathematics Syllabus 20-21 – Chapters, Topics.

The syllabus was the same as the previous syllabus. But, the Marks obtained for the units were different compared to the last year. So, we have given the units and the marks of the units of 2021.

So, we also mentioned the PDF of CBSE Class 12 Mathematics Syllabus 2021. So, the students can also can download the syllabus which was in a PDF.
