Hello,

The score of 3 subject add with the English mark to create total score.

The total score then divide by 4 and get average score. And multiply with 100 .

Average mark from subject examination from class 11 to class 12 60% Weightage.

Further internal Assessment and project work and practical Assessment is 30% weightage

Average mark from class 10th 10% weightage.

So to calculate the final 12 th grate percentage we add 11 and 12th weightage of 60 % and also the internal Assessment of 11 and 12 add . And final result create by adding the 10th grade 10% weightage also.

All the best!!
