Understanding Your GPA Calculation
The Grade Point Average (GPA) is the standard metric used by colleges and high schools to measure academic performance. It is a weighted average that takes into account both the grades you receive and the number of credit hours each course is worth.
How GPA is Calculated
To calculate your GPA manually, you follow a simple formula related to "Quality Points." Quality points are calculated by multiplying the grade value (0.0 to 4.0) by the credit hours of the course.
The Formula:
GPA = Total Quality Points ÷ Total Credit Hours
For example, if you take a 3-credit class and earn an 'A' (4.0), you earn 12 quality points (3 × 4.0). If you take a 4-credit lab and earn a 'C' (2.0), you earn 8 quality points (4 × 2.0).
Total Quality Points: 12 + 8 = 20
Total Credits: 3 + 4 = 7
GPA: 20 ÷ 7 = 2.85
Standard 4.0 Grading Scale
Most institutions use a standard 4.0 scale, though some include plus/minus grading which affects the point value slightly.

Semester vs. Cumulative GPA
Semester GPA reflects your performance in a single academic term (e.g., Fall 2023). It is calculated using only the courses taken during that specific timeframe.
Cumulative GPA (also known as Overall GPA) is the average of all grades earned throughout your entire academic career at the institution. To raise a cumulative GPA, you must consistently earn grades higher than your current average in subsequent semesters.
Why Your GPA Matters
Maintaining a healthy GPA is crucial for several reasons:
Financial Aid: Many scholarships and grants require maintaining a minimum GPA (often 2.5 or 3.0).
Graduate School: Admissions for Master's and PhD programs are highly competitive and weigh undergraduate GPA heavily.
Employment: Some competitive industries (like finance and engineering) may ask for GPA on entry-level job applications.
