Weighted vs Unweighted GPA: What's the Difference?
A weighted GPA is a calculation system used by high schools to represent academic rigor. Unlike the standard unweighted scale, which treats all classes equally, a weighted scale rewards students for taking more difficult courses.
In the United States, advanced classes like Advanced Placement (AP), International Baccalaureate (IB), and Honors courses are assigned extra weight. An A in a standard class is worth 4.0 grade points, but an A in an AP class is worth 5.0 grade points. This allows students taking challenging schedules to earn a GPA above 4.0, demonstrating academic ambition to college admissions committees.
How to Calculate Weighted GPA
To calculate weighted GPA, convert grades to point values incorporating bonus points for course difficulty:
- Unweighted GPA: Measured on a 0.0 to 4.0 scale. An 'A' is worth 4.0 points regardless of class difficulty (whether it is remedial math or AP Calculus).
- Weighted GPA: Measured typically on a 0.0 to 5.0 scale. It adds +1.0 point for AP and IB courses, and +0.5 points for Honors classes to reward academic courage.
Why do colleges care about Weighted GPA?
College admissions offices prioritize applicants who push themselves. A student with a 3.8 unweighted GPA who took 8 AP classes is often viewed more favorably than a student with a 4.0 unweighted GPA who took only basic courses. The weighted GPA allows colleges to see at a glance how well you performed relative to the difficulty of your course load.
Our weighted GPA calculator simulates this dynamic by automatically applying weight points when you select the 'AP/Honors' checkbox for a course. Try toggling between the scales to see how your GPA shifts.
