High School GPA Basics
Your high school GPA is one of the most important factors in college admissions. It represents your overall academic performance across all four years of high school. Understanding how GPA works—and how to improve it—gives you a strategic advantage in the application process.
Unweighted vs Weighted in High School
Most high schools track two types of GPA:
- Unweighted (4.0 scale): All classes treated equally. An A in any class = 4.0.
- Weighted (5.0 scale): AP, IB, and honors classes get bonus points. An A in AP = 5.0.
Learn more about the differences in our weighted vs. unweighted GPA guide.
How High School GPA is Calculated
The formula is the same as college GPA:
- Convert each letter grade to grade points
- Multiply by the course's credit value (usually 0.5 per semester or 1.0 per year)
- Sum all quality points and divide by total credits
Example: Sophomore Year GPA
| Course | Credits | Grade | Quality Pts |
|---|---|---|---|
| Algebra II | 1 | B+ (3.3) | 3.3 |
| English II | 1 | A (4.0) | 4.0 |
| AP World History | 1 | A- (3.7) | 3.7 |
| Biology | 1 | A (4.0) | 4.0 |
| Spanish II | 1 | B (3.0) | 3.0 |
| Art | 1 | A (4.0) | 4.0 |
Unweighted GPA = 22.0 ÷ 6 = 3.67
What GPA Do You Need for College?
| College Type | Typical GPA Range |
|---|---|
| Ivy League / Elite | 3.9 – 4.0 unweighted |
| Highly selective | 3.7 – 3.9 |
| Selective | 3.3 – 3.7 |
| Moderately selective | 3.0 – 3.3 |
| Open admission | No minimum |
Remember: GPA is just one factor. Admissions also consider test scores, essays, activities, and course rigor. Read more in our GPA and college admission guide.
