Hello,

Whether you have scored less marks in a subject you can still calculate the percentage of marks scored in all subjects. If you want to calculate the overall aggregate percentage you can calculate it by adding the marks scored in all subjects and dividing it by the total score. For example if you have scored 80, 55,75, 64, 90, 45 in Maths, Biology, Physics, Chemistry, English and Hindi respectively you need to add all the marks. After adding the sum is 409 marks now let's consider that the total marks for each subject is 100 marks adding up the total marks it sums up to 600. So the percentage now become (sum of marks scored in all subjects/total marks)x100= (409/600)x100=68.1%

So the overall aggregate percentage is 68.1%.
