Key Features of the New Grading System
The New Grading System of CBSE Class 12 focuses on holistic evaluation rather than rote memorization.
-
Competency-Based Assessment: 2026 exams feature a higher percentage of application-based questions (approximately 50%) to test real-world understanding.
-
Holistic Weightage: The final result is a combination of Internal Assessments (20 marks), Practical Exams (30 marks), and Theory (70-80 marks).
-
Tie-Breaking Policy: If multiple students score the same marks, they are awarded the same grade, ensuring no student is unfairly penalized by decimal differences.
Advantages and Disadvantages of the Relative Grading System
The Benefits
-
Reduces Academic Pressure: Students focus on staying in the top bracket rather than obsessing over a single mark.
-
Standardization: If a specific subject paper is exceptionally difficult, the relative grading ensures students still receive high grades based on the top percentile.
-
Skill-Oriented: Encourages performance in internals and practicals, promoting consistent learning throughout the year.
The Drawbacks
-
Ambiguity: Scores of 91 and 100 may both result in an A1, which can be seen as a lack of differentiation for high achievers.
-
Cohort Dependence: A student's grade is partially dependent on how the rest of the student body performs in that specific year.
