CBSE Class 9 Syllabus 2020-21 All Subjects

CBSE has released Class 9 revised syllabus of all subjects English, Hindi Course A and B, Maths, Science, Social Science, Sanskrit, Computer and Home Science. Keeping in the view of Coronavirus pandemic, the board has decided to reduce syllabus by 30 percent.

According to Board 'The prevailing health emergency in the country and at different parts of the world as well as the efforts to contain the spread of Covid-19 pandemic has resulted in loss of class room teaching due to closure of schools. Therefore the Board has decided to revise the syllabi for classes IX-XII for the academic session 2020-21.'

CBSE in their statement added 'Considering the importance of achieving the level of learning, the syllabus has been rationalised to the extent possible by retaining the core concepts. The Heads of Schools and Teachers may ensure that the topics that have been reduced are also explained to the students to the extent required to connect different topics. However the reduced syllabus will not be part of the topics for Internal Assessment and year-end Board Examination.'

Various topics have been dropped from the syllabus such as in Science definition of matter, thrust and pressure, Archimedes’ principle and various others. In Social Science Syllabus, the board removed drainage and population chapters from geography and Livelihoods, Economies and Societies in history. Also, in English and Hindi, the board has decided to remove various stories and poems and also grammar section. To view detailed syllabus you can click on the subject wise syllabus below.

CBSE Class 11 Maths Syllabus 2020-21| Check Latest Exam Pattern

CBSE has released revised Class 11 Maths Syllabus 2020-21. This year, the board has decided to reduce the syllabus by 30 percent.  The annual board examination will be of 80 marks, while internal assessment (Periodic Tests and Mathematics Activities) will be of 20 Marks.

No.	Units	Marks
I	Sets and Functions	23
II	Algebra	30
III	Coordinate Geometry	10
IV	Calculus	07
V	Statistics and Probability	10
-	Total	80
-	Internal Assessment	20

In Board examination, the listed topics will come. The written examination will be of 80 marks. No chapter/unit-wise weightage is given. There will be no overall choice in the question paper. However, 33% internal choices will be given in all the sections
