How Will Class 12 Results Be Calculated? CBSE Marking Formula


The Central Board of Secondary Education (CBSE) recently released details on how Class 12 students will be marked in lieu of the canceled exams that occurred due to COVID-19.


The CBSE announced more than two weeks ago the cancellation of board examinations for Class 12 and yesterday, 17 June, revealed details of how students would be marked for the board exams.

This article will cover the components and formulas that CBSE uses to both assess and mark students.

  • For the theory part of the course, students would be marked based on their performance in Class 10 Board exams and exams conducted by the school at Class 11 and 12.

  • For practicals, marks will be assigned based on the results of the student in practicals or internal assessment, as conducted by schools.

For calculating marks, the board has relied on scores from the last three years only. However, it is important to remember that performance in Classes 11 and 12 were taken into account for awarding only theory segment marks.

As an example, let’s say that the theory component of the class 12 subject carries 70 marks. But for this year, as no theory exams were conducted, the board would calculate these marks in the following way.


Class 10: 30 percent of 70 marks (21) would come from the performance of students in CBSE Class 10 board exams which would include the “theory component of best three subjects out of five main subjects".


Class 11: 30 percent of 70 marks (21) would come from marks obtained by students in the theory component of the final exam of Class 11.


Class 12: The remaining 40% of 70 marks (28)would be based on unit tests, midterm exams, and preboard exams.


For the theory component of their Class 12 exam, students’ performance for all three years will be taken into account. For the practical component of their Class 12 exam, real marks scored by him/her in class 12 practicals will be considered.


The result committee of a school can decide the weightage to be given to unit tests, midterms, and pre-board theory examinations. Students need to understand that if the committee decides pre-board examinations should be taken into consideration, full weightage will be given to it. In some cases, when students have not appeared for any or more than one exam, the CBSE will evaluate the situation and determine an appropriate assessment.


Although marks in Class 10 are calculated based on a standardized pattern, those obtained by students in Classes 11 and 12 (pre-boards and unit tests) differ depending on the marking system adopted by schools.

Schools will have to internally moderate the marks they give students for Class 12 by calculating a host of other factors, in order to account for variations from school to school or even classroom to classroom. These are called ‘moderation points’.


Your school's past performance in the Board exams will be taken into account when calculating your marks.

For example, if a school's performance for 2017-2018 is 80 percent, and that number is considerably higher in 2018-2019 and 2019-2020 at 90 percent.


Then the 2018-2019 year will be used as a benchmark for moderation.
