Formula and Calculation

The conversion from a different grade scale to the 15-point scale is calculated using the following formula:

15-Point Grade = (Original Grade / Maximum Possible Grade) × 15

Where:

Original Grade - Your grade on the original scale
Maximum Possible Grade - The highest possible grade on the original scale

For example, if you scored 85 out of 100 on a test, the calculation would be:

15-Point Grade = (85 / 100) × 15 = 12.75

This means your grade of 85 on a 100-point scale converts to approximately 12.75 on a 15-point scale.

Interpreting Your 15 Point Grade

The 15-point scale is typically interpreted as follows:

15-Point Grade	Interpretation
13.5 - 15	Excellent
10.5 - 13.4	Good
7.5 - 10.4	Satisfactory
4.5 - 7.4	Needs Improvement
0 - 4.4	Unsatisfactory

This interpretation can vary slightly depending on the institution, but it provides a general guideline for understanding your performance.
