How to Calculate High School GPA

Grade Point Average (GPA) is a standard method of calculating a student's average grade over their high school career. It's widely used in high schools across the United States and is an important factor in college admissions. Here's a comprehensive guide on how to calculate high school GPA:

High School GPA Formula

The basic formula for calculating high school GPA is:

\(GPA = \frac{\text{Total Grade Points}}{\text{Total Credits}}\)

Where:

• Total Grade Points = Sum of (Grade Point × Credit) for each course
• Total Credits = Sum of credits for all courses

Calculation Steps

1. Assign a numerical value to each letter grade (e.g., A = 4.0, B = 3.0, etc.)
2. Multiply each course's grade point by its credit hours
3. Sum up all these products to get the total grade points
4. Sum up all the credit hours
5. Divide the total grade points by the total credit hours

Example Calculation

Let's calculate the GPA for a high school student with the following grades:

• English: A (4.0), 1 credit
• Math: B+ (3.3), 1 credit
• Science: B (3.0), 1 credit
• History: A- (3.7), 1 credit

1. Calculate grade points for each course:
   • English: 4.0 × 1 = 4.0
   • Math: 3.3 × 1 = 3.3
   • Science: 3.0 × 1 = 3.0
   • History: 3.7 × 1 = 3.7
2. Sum up total grade points: 4.0 + 3.3 + 3.0 + 3.7 = 14.0
3. Sum up total credits: 1 + 1 + 1 + 1 = 4
4. Calculate GPA: 14.0 ÷ 4 = 3.5

Therefore, the student's GPA is 3.5.
