It is calculated according to the score ratio of papers and subjects. Multiply the scores of each subject by weighted values, tenths, etc., and then add up the scores. For example, there is a credit system in universities, which requires weighted scores, that is, multiplying the scores of each subject by the credits and adding them up.

Finally, divided by the sum of credits, your weighted average is the average score calculated by multiplying each score by its weight ratio. The algorithm multiplies each score by its weight ratio. The calculation of weighted average score is similar to GPA algorithm. Examples of different meanings

Four credits for advanced mathematics and six credits for circuit theory. The credit of the subject is the weight of the subject. So the weighted score is the subject score multiplied by the credit value of the subject, and the weighted average score is the sum of the weighted scores of all subjects divided by the total credit.
