Discover how GPA is calculated, the difference between weighted and unweighted GPA, and tips to improve your grade point average.
Your Grade Point Average (GPA) is one of the most important metrics in your academic career. Understanding how it's calculated and how to improve it can significantly impact your educational opportunities. This guide covers both weighted and unweighted calculations - for a detailed comparison of these systems, read our weighted vs. unweighted GPA guide.

What is GPA?
GPA stands for Grade Point Average. It's a numerical representation of your academic performance, typically on a scale of 0.0 to 4.0 in the United States.
Standard GPA Scale
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
How to Calculate Unweighted GPA
Unweighted GPA treats all courses equally, regardless of difficulty:
- Convert each letter grade to its point value
- Add all grade points together
- Divide by the total number of courses
Weighted vs. Unweighted GPA
Weighted GPA gives extra points for advanced courses like AP, IB, or Honors classes. These courses typically use a 5.0 scale instead of 4.0, rewarding students for taking more challenging coursework. For step-by-step instructions on calculating these complex grades, see our weighted grades calculation guide.
Calculating Weighted GPA
For weighted GPA:
- Regular courses: Use standard 4.0 scale
- Honors courses: Add 0.5 points (A = 4.5)
- AP/IB courses: Add 1.0 point (A = 5.0)
Tips to Improve Your GPA
1. Focus on Current Courses
Your current grades have the most immediate impact. Prioritize assignments and tests in your ongoing classes.
2. Take Advantage of Extra Credit
When available, extra credit opportunities can boost individual course grades and your overall GPA.
3. Consider Course Load
Taking weighted courses can improve your weighted GPA, but only if you can maintain good grades in them.
4. Use Grade Calculators
Regularly track your progress with a grade calculator to stay informed about your academic standing and make strategic decisions. For students who prefer hands-on approaches, our Excel calculator tutorial shows you how to build your own tracking system. And when finals approach, don't miss our final exam strategy guide.
