How to calculate percentile when we know the marks

Hello aspirant,

Firstly, calculate the percentage you received on the test by dividing your mark by the total marks.  For example,  if
You scored 18 out of 20,.then 18/20=90 present. Secondly,  multiply your percentage score on the test by the percentage it is worth of the final grade.Teachers in high school and college often calculate semester grades by assigning weights to assignments throughout the semester and computing a weighted average, or weighted mean. , If you knew your scores in each of these categories,you can find out your grade by calculating a weighted value for each category.

Hope you understand,
Thank you
