CBSE Marking Scheme 2021-22
A student will take the board exams twice in their lives. One is in Class 10 and the other is in Class 11. Students’ grades in Class 10 help them understand the topics in which they excel, while their grades in Class 11 help them plan their future. In order to make it easier for students to study all of the concepts, the CBSE board has divided the entire syllabus into two terms. After studying the CBSE board’s revised course structure, students will be able to comprehend the chapters that are worth more marks and practice them effectively.
