CBSE Board New Syllabus 2021

The whole world is suffering from an epidemic named COVID-19. Due to this, the lockdown was implemented across the country to the Government of India. Looking at the economic conditions of India, the government has removed lockdown, but schools, colleges, institutes are still shut down. And this has created a big hassle for both students and teachers.


To resolve the problem and to reduce the stress of scholars, Dr. Ramesh Pokhriyal Nishank has taken a step to rationalize the syllabus of class IX to XII. However, some people are in opposition to this decision, but this doesn’t make any difference.


HRB Minister stated that the eliminated syllabus will be covered under the alternative academic calendar. CBSE officials informed all schools that the syllabus reduced from the course can be taught by teachers for a better understanding of topics, but these lessened topics will not be a portion of internal assessment or the course for a final assessment of boards.

NCERT Alternative Academic Calendar 2020-21

National Council of Educational Research and Training will prepare “Alternative Academic Calendar” for class 1st to 12th. The expected calendar of CBSE 2020-21 will concentrate on how to use technology to assist and promote the approach of learning. The motive of publication of an academic calendar for students and teachers to maintain the continuity of e-learning classes. It is required to keep involved all children and provide learning classes at home.

Hot talks happening in Society About CBSE Board New Syllabus 2021

Many groups in our society are raising their opinions since HRD Minister has lessened the 30% of CBSE syllabus. According to our analysis, some people are in favor of syllabus reduction, and some are not. Dr. Ramesh Pokhariyal has tweeted and responded to all those people who have doubts related to the insertion and elimination of topics.

Politicians and educationists had been disputing the decision of reduction of the syllabus. HRD Minister Dr. Ramesh Pokhariyal stated that “The sole purpose is to relax the pressure on students by diminishing the curriculum by 30%. This activity has been brought out by following the advice & support of several specialists and recognizing the suggestions received from educationists through our #SyllabusForStudents2020 campaign”.


Whereas many people are considering the decision of HRD minister in a positive direction. Impact of coronavirus is hitting people of India so hard that schools/ institution/ colleges/ universities are still closed, and it is becoming difficult to start the new class with a huge syllabus. So, to reduce the stress of students authorities has cut the syllabus by 30%. Now it has become easy to learn and understand the rest topics more efficiently.

Hence, people will consider the topic in both negatively and positively. But from our understanding in this pandemic, it is a great decision for all students where many scholars don’t have any medium to study still they are learning from various sources.
