How is the CBSE Grading System 2024 for Class 12 operated?

The CBSE class 12 grading system has been designed to decrease the ranking of students based on their marks and competition among the top students. Each student is assigned grades according to the marks they achieve. The CBSE grading system for class 12 is structured around a 9-point grading scale. This class 12 grade system will be utilized for calculations. The grading scales are arranged alphabetically, with A, B, C, D, and E being the most significant.

Some Key Points About the CBSE Grading System

  • If there is a tie or scores fall within a certain range, the same grade will be given to all pupils. If needed, the smaller group of pupils will be merged with the larger group.
  • This grading scheme will only be applied to subjects with more than 500 passing applicants.
  • Subjects with fewer than 500 passing candidates will be graded according to patterns used in similar subjects.
  • Grades will be calculated based on the results of external examinations, while schools will assign grades for internal exams.
  • The CBSE grading system uses two parameters: Percentile and Absolute Marks.
  • Depending on the subject, criteria for grading may vary. Hence, students will only receive grades specific to each subject, without an overall cumulative grade.
  • Minor adjustments will be made in the proportion of candidates to resolve ties in the CBSE grading system.
  • If there’s a need to divide a score point into two groups, the smaller group will be combined with the larger one.
  • An interesting aspect of the CBSE grading system in 2023 is that students scoring 71 marks will receive the same grade as those scoring 80 marks.

Here’s how your percentage for CBSE Class 10 and Class 12 can be calculated:

For CBSE Class 10:

Your percentage for class 10 results under CBSE grading system can be calculated in the following way:

Step 1: The grade points for all major subjects are added together in the first step.

Step 2: This total is then divided by 5.

Step 3: The result from step 2 is multiplied by 9.5. This will give you the percentage.

For example,

If your total grade points are 40.3,

The sum is divided by 5.

40.3 divided by 5 equals 8.3

When 9.5 is multiplied by 8.3, it equals 78.85%

For CBSE Class 12:

The percentage of class 12 CBSE scores can be determined using the following steps:

Step 1: Add up the scores from the board tests for the CBSE 12th grade in all five major subjects.

Step 2: Divide the total by 5.

Step 3: The percentage earned on the CBSE class 12th board exam is the result of this calculation.


A variety of benefits are brought about by giving out grades instead of numerical marks. The variation in marking between examiners is significantly lowered. Flaws in the assessment tools are also addressed by this method. According to a statistical study on evaluation methods, there is a chance that ratings given to people could vary by up to 15%. All of these irregularities in evaluation methods are automatically corrected by placing students with equal potential in the same ability bands (grades). Last but not least, unfair comparisons of minor differences in scores will be lessened.
