CBSE class 12 reduced 30% syllabus details 2020-2021 | CBSE new syllabus 2020-2021: We all are aware of the pandemic situation from which the whole world is suffering. The spreading of Corona virus is not reducing and it is continuously increasing it's patient number. The only way to be safe from it is to make social distance and stay at home. Government is taking many steps to control it's effect but is not found fruitful to good amount.

Many things is going worst such as budget of the country, education, transportation, and business of many people. Government is distributing free food materials to all the families but it will also be hard if the condition remains same. Keeping these things aside, the most heavy problem is facing those students who have board exams in session 2020-2021.
They are not getting proper education because all the schools and colleges are closed at this pandemic condition. CBSE has told every school and colleges to teach students through online classes. But this can't fulfill the class environment and other thing is that many students doesn't have smartphones to attend online classes.
So keeping all these things in mind, CBSE has reduced 30% of the total syllabus. This has been done because the syllabus of Class 12 is very much considering the time left for the class 12 board exam. This reduction in syllabus is done in very detailed way that will be explained further here. Also the topics are removed on the basis of importance of those topics. It has no guarantee through CBSE that any of the removed topic will come in competitive questions or not. Here below are the details of CBSE class 12 reduced 30% syllabus details 2020-2021.

What is the benefits of 30% reduced syllabus by CBSE for class 12 ?
• After the reduction of syllabus, both students and teachers will find it easier to complete the syllabus at time. The reduction in topics from each chapter can simply be skipped considering the board exam. Many questions have also been removed from the exercises that can be skipped while studying.• Students will get much time to complete a topic and they can fully concentrate on a particular topic. Teachers also can take their time to explain any topic so that every student can understand it.
What are the demerits behind reducing 30% syllabus by CBSE for class 12 ?
All students are happy that the syllabus has been reduced but it is the fact that reduction in syllabus will directly affect the study materials of all the students.
• The reduced syllabus will not be taught in school and colleges due to which students will miss the knowledge of those topics. The actual study of class 12 will be effected and students will be in loss. Another thing is that, some topics are correlated that may be from deleted topics. This can be found a trouble for the students as they would have not studied that topic.
• The topics that are reduced for CBSE exam pattern is not necessary that those questions will not come in competitive exams such as IIT or NDA. So if a student wants to prepare for competitive exams, then he/she has to study full syllabus anyhow. But for CBSE board exams, a student can go through this blindly to score good marks.
