Dear Nandini,

To understand, students may please note that the final score of CBSE subjects has two components – theory and practical. Depending on the subject, the practical component varies from 50 marks to 20 marks. For the computation of Class 12 Results, the practical marks scored by students would be taken as it is.

For the theory component, which conversely would be 50 marks to 80 marks, CBSE has proposed a 30:30:40 ratio split. In other words, to calculate the marks of Class 12 theory papers, schools would give 30% weight to Class 10, 30% to Class 11, and 40% to Class 12.

It is again reiterated that only the theory marks would be calculated with the formula of 30:30:40. The practical marks scored by the students would be taken as it is. The same is tabulated below.

30% of Class 10

Also, for Class 10 marks, CBSE would take the average marks of the best three performing subjects. What is important to remember is that only the theory paper marks would be considered. To explain it further, let’s consider the Class 10 mark sheet below.

Now, as per the given marks, the student has the best performance in English, Science, and Social. The average marks for the Class 10 component would be (74+70+68)/3 which would be 70.67 and not (94+90+88)/3 which is 90.67. Now, these marks would be then scaled based on whether the theory was for 80 marks or 70 or 50.

For an 80-mark paper, the 70.67 would then be converted to marks out of 24 or 70.67 of 24, which would come out as 21.2 marks. Similarly, for a subject like Physics, where the theory is out of 70, the calculation of Class 10 marks would be out of 21, which would be 18.55 marks, and so on.

30% of Class 11

This is rather a straightforward calculation. Schools have to consider only the final score of the theory component of the subjects chosen by the student. While the average score of Class 10 was taken as one score, for Class 11, the schools would take the final marks of Class 11 exams in that particular subject and compute it.

So, say a student scored 65 out of 80 in English in Class 11, for tabulation purposes, the school would take the same score. For this, the student would be 19.5 out of 24 in the final tabulation.

40% of Class 12

For Class 12, the resulting committee set by the school would decide the marks that would be considered. The schools may consider a weighted average of mid-terms and pre-boards or only the pre-board result. This again would be the marks scored in theory. Now, again, for convenience, let us presume the school decides to take the average score of students’ pre-board examination only.

Now, taking an example again, say out of 80 the student scored 70 in English in the pre-board exams. Now, the school would compute these marks out of 40% or 32, which comes out to be 28.

How final CBSE Class 12 Results would be tabulated?

Now, taking the same example as mentioned above, the Class 12 marks for the student in English, say if he scored 20 in practical examinations, would be as follow.

Students and parents may please note that this is only a tentative plan. The marks provided above are only for reference. Also, the criteria for class 12 would differ from school to school. Furthermore, once the score is calculated, the same would then be subjected to moderation, like in Class 10 where the result of the school of the past three years would be considered.

Hope it was helpful.
