What is GPA?
Grade Point Average (GPA) is a numerical representation of your academic performance. Each letter grade is converted to a number (A=4.0, B=3.0, etc.), and the average is weighted by credit hours.
How GPA is Calculated
The formula is straightforward: multiply each course's grade points by its credit hours, sum them up, then divide by total credit hours.
Step 1: Convert letter grades to points: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0
Step 2: Multiply each grade point by the course's credit hours
Step 3: Sum all weighted points, divide by total credit hours
Example Calculation
Suppose you're taking 4 courses this semester:
| Course | Credits | Grade | Points |
|---|---|---|---|
| Math 101 | 4 | A | 16.0 |
| English 201 | 3 | B+ | 9.9 |
| Physics 101 | 4 | A- | 14.8 |
| History 101 | 3 | B | 9.0 |
GPA = (16.0 + 9.9 + 14.8 + 9.0) / (4 + 3 + 4 + 3) = 49.7 / 14 = 3.55
Weighted vs Unweighted GPA
- Unweighted GPA: Uses the standard 4.0 scale regardless of course difficulty. An A in regular Math = an A in AP Math.
- Weighted GPA: Adds extra points for honors/AP/IB courses. An A in AP Math might be worth 5.0 instead of 4.0.
- Cumulative GPA: Your overall average across all semesters, not just the current one.
- Major GPA: Some employers look at just your major-specific courses, which can be higher or lower than your cumulative.
Strategies to Improve Your GPA
- Retake low-grade courses: Many schools replace the old grade in GPA calculations when you retake a course.
- Balance your course load: Mix harder courses with lighter ones to maintain a strong semester GPA.
- Focus on high-credit courses: A grade improvement in a 4-credit course has more impact than in a 1-credit course.
- Use a GPA calculator before each semester: Plan what grades you need in each course to hit your target GPA.
- Don't ignore plus/minus grading: A B+ (3.3) vs B (3.0) can make a noticeable difference over many courses.
