Step-by-Step Manual Calculation

Step 1: Create a Table

Write down each course, its credits, its grade, and leave a column for quality points.

Step 2: Convert Calificacións to Points

Use the table above to find the numeric value for each letter grade.

Step 3: Calculate Quality Points

For each row, multiply: Créditos × Puntos = Quality Points.

Step 4: Sum the Columns

Add up all quality points. Add up all credits.

Step 5: Divide

GPA = Total Quality Points ÷ Créditos Totales. Round to two decimal places.

Worked Example

CourseCréditosCalificaciónPointsQuality Pts
Math3B+ (3.3)3.39.9
Science4A (4.0)4.016.0
English3B (3.0)3.09.0
PE1A (4.0)4.04.0

Sum of Quality Points: 9.9 + 16.0 + 9.0 + 4.0 = 38.9

Sum of Créditos: 3 + 4 + 3 + 1 = 11

GPA = 38.9 ÷ 11 = 3.54

Quick Estimation Trick

For a rough estimate: if most of your courses are B-range (3.0), and you have a few A's, your GPA will be somewhere between 3.0 and 3.5. Each A in a 3-credit course adds about 0.06–0.10 to your GPA above the B baseline (depending on total credits).
