CBSE Marking Scheme 2024-25

A student will take the board exams twice in their lives. One is in Class 10 and the other is in Class 12. Students can use their Class 10 scores to better understand the topics in which they excel, and their Class 12 grades can 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.

The 12th grade is a critical year in a student’s life. To help students understand all of the concepts quickly, the CBSE board divided the entire course into two terms of equal marks. All of the chapters are divided into divisions based on their importance in terms of the board exam and their weight in terms of marks. The mission is to provide Class 12 students with a high-quality education and to support them in reaching their long-term goals. It also provides a strong foundation in core topics that are important for board exams.
