Getting the updated  CBSE Class 12 syllabus 2020-21 is important as CBSE has reduced the syllabus by 30%. It is important to note the syllabus in order to do the preparation at the best level. If one is well acquainted with the syllabus part then it becomes a smooth process to study and learn. The syllabus contains all the chapters that will be covered in the curriculum of CBSE class 12th Boards exams for students in Science, Commerce, and arts stream. IT also helps us to know the marking scheme and the weightage of each chapter.

Subjects like physics, biology, chemistry, maths, computer science have high weightage on practicals, hence CBSE class 12th syllabus allows students to know the syllabus for that too.

The necessary addition and deleted chapters are also well defined in the syllabus.

Vidya Setu is one such online learning portal that has identified the importance of an updated syllabus in study routine. They provide the best study materials that cover the latest syllabus approved by CBSE. At the same time, it helps in the comprehensive learning process and creates strong conceptual understandings of the chapters.

They also provide free online video lectures to the students and make their learning process easy.

Purpose Of The CBSE Syllabus for class 12th 

The CBSE curriculum is set up every year that defines the role of examiner and examinee(teacher and students). The main objective of the curriculum is to interlink the primary goals of the educator and the learner. 
It helps the examiner to follow the rules and regulations while conducting the examinations for class 10th to 12th. They also set the parameters on which every student will be assessed and will grant marks accordingly. To meet the educational requirements of the candidates those parents were employed in transferable jobs. To prescribe and update the courses of instructions for examinations. To affiliate institutions for the purpose of examination and raise the academic standards of the country.
The Board also promotes Innovations in teaching and learning methodologies by devising student-friendly and student-centered paradigms. Reforms in examinations and evaluation practices.Skill learning by adding job-oriented and job linked inputs. Regularly updating the pedagogical skills of the teachers and administrators by conducting in-service training programs, workshops, etc.

Importance of Class 12 CBSE Syllabus

The syllabus is very important as it is a well-defined structure of what to learn, how to learn, from where to learn,  and how the learning will be assessed. The syllabus is an unsaid contract between teachers and students on how the entire session learning will progress.

The syllabus communicates information that establishes an agreement between the teacher and students to deliver education and how to deliver it. We know the syllabus needs strategies to provide guidelines to the students so that they don’t take advantage of the unstructured curriculum. What is required to create a better education environment is, “interactive modulation.” A platform where students can share and discuss the new opportunities and the CBSE panel can integrate their constructive suggestions in the latest syllabus. We could all benefit from the discussion of these syllabus-related issues, and we encourage you to share your thoughts in the comment below ‌
