What Is GPA and Why It Matters

GPA, or Grade Point Average, is one of the most important numbers in your academic life. Whether you're applying to colleges, scholarships, or even internships, your GPA tells others how well you've performed in school. But what exactly is GPA and how is it calculated?

At its core, GPA is the average of your grades, converted into a point system (usually on a 4.0 scale). The higher your GPA, the better your academic performance.

Types of GPA and What They Mean

1. Unweighted GPA

An unweighted GPA is calculated on a traditional 4.0 scale, where every course is treated equally—whether it's a regular class or an AP-level course.

  • Example: An A in P.E. is worth the same as an A in AP Chemistry.
  • Scale: Maxes out at 4.0

2. Weighted GPA

A weighted GPA adds extra points for more challenging courses like AP, IB, or Honors.

  • Example: An A in an AP class may be worth 5.0 instead of 4.0
  • Scale: Can go up to 5.0 or higher, depending on the school

3. Cumulative GPA

Your cumulative GPA is the average of all your grades across every semester or grading period since you started high school (or college).

  • Used for: Transcripts, college applications, honors calculations

4. Semester vs. Quarter GPA

  • Semester GPA is calculated based on your performance over half the academic year.
  • Quarter GPA is based on shorter grading periods (usually 9–10 weeks).
  • Both are important, but cumulative GPA combines them all for the big picture.

GPA Scale Conversion Table

Understanding how your grades translate into GPA points is essential when calculating your GPA. Most schools in the U.S. use a 4.0 GPA scale, but many offer weighted GPAs for advanced classes like Honors, AP (Advanced Placement), or IB (International Baccalaureate).

Use the conversion table below to see how letter grades and percentages align with both unweighted and weighted GPA scales:

Letter Grade Percentage Range Unweighted GPA (4.0 Scale) Honors GPA AP / IB GPA
A+ 97–100% 4.0 4.5 5.0
A 93–96% 4.0 4.5 5.0
A− 90–92% 3.7 4.2 4.7
B+ 87–89% 3.3 3.8 4.3
B 83–86% 3.0 3.5 4.0
B− 80–82% 2.7 3.2 3.7
C+ 77–79% 2.3 2.8 3.3
C 73–76% 2.0 2.5 3.0
C− 70–72% 1.7 2.2 2.7
D+ 67–69% 1.3 1.8 2.3
D 65–66% 1.0 1.5 2.0
F Below 65% 0.0 0.0 0.0

How to Use This Table

  • Unweighted GPA: Standard 4.0 scale (used for most regular classes)
  • Honors GPA: Adds 0.5 points to GPA scale for more advanced classes
  • AP / IB GPA: Adds 1.0 point to GPA scale for college-level classes
