Understanding Percentage Grades
Percentage grades are a common way to represent academic performance, providing a numerical value that indicates a student’s level of achievement. They are calculated by dividing the number of points earned by the total number of points possible and multiplying the result by 100.

Calculating Percentage Grade
In your case, you scored 13 out of a possible 20 points. Using the formula above, we can calculate your percentage grade as follows:
Percentage Grade = (Number of Points Earned / Total Points Possible) x 100
Percentage Grade = (13 / 20) x 100
Percentage Grade = 65%
Therefore, your score of 13/20 equates to a percentage grade of 65%.
Grading Scales
Different educational institutions may use slightly different grading scales, but the most common scale is as follows:
Letter Grade | Percentage Range |
---|---|
A | 90-100% |
B | 80-89% |
C | 70-79% |
D | 60-69% |
F | Below 60% |
Based on this scale, your grade of 65% would fall into the “C” range.
Interpreting Percentage Grades
Percentage grades provide a standardized way to compare student performance across different assessments and assignments. They can also be used to track progress over time and identify areas for improvement.
It is important to remember that grades are just one measure of academic achievement. They should not be considered the sole indicator of a student’s knowledge or abilities. Other factors, such as effort, engagement, and growth mindset, should also be taken into account.
