Dear Student,

First you need to download the result from the official website of cbse which is cbseresults.nic.in then you just need to add the whole marks of all subject then divide that with sum of maximum marks of all  the subject multiplied by 100. So that you can find your percentage.

(sum of the each subject marks) / (sum of the maximum marks of each subject) x 100.

Best Of Luck!!!

Hey,

If you want to calculate the class 12 result marks, in terms of percentage obtained, then, the basic thing you need to do is add up all the scores obtained the subjects, multiply with the 100 and then divide with the number of subjects multiplied with 100.

For example,

You have 5 subjects, and you have obtained 90 marks in all the 5 subjects. Then, your percentage will be

90+90+90+90+90/500*100= 90%

The result will be released at www.cbse.nic.in or www.cbseresults.nic (//www.cbseresults.nic) .in
